I have a problem when run command: sudo -su user_test ./pgsql/bin/initdb -D /example/folder
I had researched many sources from the internet but don’t found a solution.
I hope everyone could help me. Thanks.

The error is thrown in BootStrapXLOG in src/backend/access/transam/xlog.c:

src/backend/utils/misc/backend_random.c says:
pg_backend_random() function fills a buffer with random bytes. Normally,
it is just a thin wrapper around pg_strong_random(), but when compiled
with --disable-strong-random, we provide a built-in implementation.
So it seems that PostgreSQL was built on a system that had a source for strong random numbers (OpenSSL or /dev/urandom, if you are not on Windows), but the facility is not working on your current system.
try with the lates minor release of v10 (currently 10.15) – maybe a bug has been fixed.
run pg_config --configure to check if PostgreSQL was built --with-openssl
OpenSSL also uses /dev/urandom, so there is likely a problem with that source of random numbers; investigate there
If all fails, build PostgreSQL from source and configure it with
./configure --disable-strong-random ...
It worked fine. Thank you very much, #Laurenz Albe

Yesterday we had crash of PostgreSQL 9.5.14 running on Debian 8 (Linux xxxxxx 3.16.0-7-amd64 #1 SMP Debian 3.16.59-1 (2018-10-03) x86_64 GNU/Linux) - Segmentation fault. Database closed all connections and reinitialized itself staying ~1 minute in recovery mode.
PostgreSQL log:

15 in libc-2.19.so[7efd322a2000+1a1000]
According to libc documentation (https://support.novell.com/docs/Tids/Solutions/10100304.html) error code 15 means:
NX_EDEADLK 15 resource deadlock would occur - which does not tell me much.
Could you tell me please if we can do something to avoid this problem in the future? Because this server is of course production one.
All packages are up to date currently. Upgrade of PG is unfortunately not the option. Server runs on Google Compute Engine.
error code 15 means: NX_EDEADLK 15
No, it doesn't mean that. This answer explains how to interpret 15 here.
It's bits 0, 1, 2, 3 set => protection fault, write access, user mode, use of reserved bit. Most likely your postgress process attempted to write to some wild pointer.
if we can do something to avoid this problem in the future?
The only thing you can do is find the bug and fix it, or upgrade to a release of postgress where that bug is already fixed (and hope that no new ones were introduced).
To understand where the bug might be, you should check whether a core dump was produced (if not, do enable them). If you have the core, use gdb /path/to/postgress /path/to/core, and then where GDB command. That will give you crash stack trace, which may allow you to find similar bug reports.
I was able to install Informix in Centos7 without much of troubles. Now that everything is setup im attempting to follow a tutorial to create a DB space. The first step is checking whether the server is up and ready using oninit -v command. But this faila with error :
bad INFORMIXSERVER
yeah, very descriptive...
Can someone help me to troubleshoot this? There is a giant lack of information about Informix on Internet so I dont know where to begin.
Informix version : 12.10
Centos version : 7
Environment variables :
-bash-4.2$ echo $INFORMIXDIR
/opt/informix
-bash-4.2$ echo $INFORMIXSERVER
miServidor
-bash-4.2$
Regards!
If you want to check if the server is up and running, run "onstat -":
informix#irk:/data/informix/IBM/12.10.FC10/tmp$ echo $INFORMIXSERVER
irk1210
informix#irk:/data/informix/IBM/12.10.FC10/tmp$ onstat -

"oninit -v" will attempt to start the server.
"oninit -V" (capital V) will show the version of the oninit binary.
informix#irk:/data/informix/IBM/12.10.FC10/tmp$ oninit -V

Check that INFORMIXSERVER env variable is set. If not you will get the following errors from 'onstat' and 'oninit':
informix#irk:/data/informix/IBM/12.10.FC10/tmp$ unset INFORMIXSERVER

We're running the Context Broker on a CentOS server but it keeps crashing with certain update queries. We've tried version 0.26 and the latest 1.0.0-1 but the result is the same, we've also tried changing the mongoDB version between 3.0.6 and 3.0.7 but no luck. The logs doesn't give us much to go on so that's why we're asking here in SO.
What we're doing is to send an update of an entity of about 1MB in size routed in from a http call via nginx. The context broker crashes (see logs below) but mongodb and other services continue to function normally.

Any ideas about what could be causing this, or where we should continue looking?
This crash is due to a bug detected at Orion. A fix is on the way, so we hope it get merged and ready to be included in next Orion release (Orion 1.2.0).
I am running fabric to automate deployment. It is painfully slow.

It takes 20 seconds before paramiko is even starting the thread. Surely, Executing task 'uptime' does not take that long. I can manually log in through ssh, type in uptime, and exit in 5-6 seconds. I'd appreciate any help on how to extract mode debug information. I made the changes mentioned here, but no difference.
Try:
env.disable_known_hosts = True
See:

&
Slow public key authentication with paramiko
Maybe it is a problem with DNS resolution and/or IPv6.
A few things you can try:
replacing the server name by its IP address in env.hosts
disabling IPv6
use another DNS server (e.g. OpenDNS)
For anyone looking at this post-2014, paramiko, which was the slow component when checking known hosts, introduced a fix in March 2014 (v1.13), which was allowed as requirement by Fabric in v1.9.0, and backported to v1.8.4 and v1.7.4.
So, upgrade !
Got system with Postgres broken (a RAID is the reason) , without any backups.
Trying to put data to another comptuter with Postgres (and make however backup).
But always when I set up data directory and run postgres I've got message
GET FATAL: database files are incompatible with server
2012-08-15 19:58:38 GET DETAIL: The database cluster was initialized with BLCKSZ 16777216, but the server was compiled with BLCKSZ 8192.
2012-08-15 19:58:38 GET HINT: It looks like you need to recompile or initdb.
It's very strange number 16777216(2 to power 24 - to big).
However I can't reset default value 8192 when compiling (playing with --with-blocksize= take no effect; BLCKSZ - I can't find it in headers files)
).
Any way to extract data ?
This is environment and circumstances:
harddrive: RAID 1 with 3 SAS disks in array

the system become broken - after some time got

First I effort to up DB in Ubuntu servers (harddisk - simple serial 2, Ubuntu 10.04 i386, Postgres 9.1) and got the same exception above (with BLCKSZ).
That's why I deployed Ubuntu 10.04 amd64 with english Postgres 9.1 (because got '?' instead of russian symbols in error logs in previous step) in virtual machine
Got the same exception (with BLCKSZ).
Ather that have removed apt-get postgres version and compiled it as described at docs http://www.postgresql.org/docs/9.1/static/installation.html.
Playing withconfigure --with-blocksize=BLOCKSIZE had take no effect - got the same error
Sorry, for the post.
The pg_contol was broken by some manipulations with.
Sow, the cluster was succeful restored by pg_resetxlog with initial data.
A blocksize of 16Mb would be really weird, and since these two values also look completely bogus:
Maximum columns in an index: 2387576020
Maximum size of a TOAST chunk: 0
...you might want to question the integrity of this data before spending time on compiling postgres with a non-standard block size.
If you look at the sizes of files corresponding to relations, are they multiple of 16Mb or 8Kb?
If the database have some gigabytes tables, what appears to be the cut-off size on disk (the size above which postgres split the data into several files)? This should be equal to data block size*Blocks per segment of large relation. On a default install, it's 1Gb.
See here for details on configuring kernel resources. Perhaps the default/current settings for this new OS won't allow the postmaster to start.
Here are details on the meaning and context of the BLCKSZ parameter. Was the system that failed running a 64bit build of PostgreSQL and the new system is a 32bit build? If possible, attempting to obtain version information on the failed system's PostgreSQL could shed light on the problem. Let us know what version, build, and OS were used. Was is a custom build?
