I'm trying to build Qt 6.4.1 using Visual Studio 2019 as a 32 bit version. When building it should also create the Qt MySQL plugin.
I already read the Qt documentation about Qt Configure Options and How to build the QMYSQL plugin on Windows and came up with the following configure command:
..\configure -prefix c:/qt/6.4.1 -debug-and-release -force-debug-info -skip qtactiveqt -plugin-sql-mysql -sql-mysql -sql-odbc -- -Wno-dev --log-level=TRACE -DMySQL_INCLUDE_DIR="C:/Program Files (x86)/MariaDB/MariaDB Connector C/include" -DMySQL_LIBRARY="C:/Program Files (x86)/MariaDB/MariaDB Connector C/lib/libmariadb.lib"
While configure.bat runs it seems to find the MySQL/MariaDB files because it does not print "Could NOT find" but "Promoting target":
...
-- Could NOT find DB2 (missing: DB2_INCLUDE_DIR DB2_LIBRARY)
-- Promoting target to global: 'MySQL::MySQL'
-- Could NOT find PostgreSQL (missing: PostgreSQL_LIBRARY) (found version "11.3")
...
Later it lists MySQL as found:
-- The following packages have been found:
* QtBuildInternals
* OpenGL
* WrapPCRE2
* WrapZLIB
* WrapHarfbuzz
* WrapPNG
* WrapOpenGL
* MySQL, MySQL client library, <https://www.mysql.com>
* ODBC
...
But finally in the summary it tells me 'no'. :-(
Qt Sql Drivers:
DB2 (IBM) .............................. no
InterBase .............................. no
MySql .................................. no
OCI (Oracle) ........................... no
ODBC ................................... yes
Does anyone know what the problem is or how to investigate further?
I already added the parameter --log-level=TRACE to get more information, but still have no clue what's wrong.
In my understanding, opening Neo4j Desktop is equivalent to starting a server. However, when I check this with invoke-neo4j status it says Neo4j is not running. Do you know why is that?
This is the verbose output:

My goal is to autostart a database and use Cypher in terminal.
Opening Neo4j Desktop is NOT equivalent to starting a server. You simply open a user interface and it requires an active connection to a running neo4j database.
For an analogy, if you open ithe door of your car and sit on the driver seat you still need to start your engine so that it will move.
While running a query on Dremio 4.6.1 installed on Kubernetes, we are getting the following error message from Dremio UI:
ExecutionSetupException: One or more nodes lost connectivity during query. Identified nodes were [dremio-executor-2.dremio-cluster-pod.dremio.svc.cluster.local:0].
Dremio-env config has the following settings:
DREMIO_MAX_DIRECT_MEMORY_SIZE_MB=13384
DREMIO_MAX_HEAP_MEMORY_SIZE_MB is not set
We are using workers of 16G /8c (Total of 10 workers)
1 Master Coordinator with the same config
Zookeeper with 1G/ 1c
Any idea what's causing this behavior ?
By doing a live logs tail before the worker crashes here are the logs:
An irrecoverable stack overflow has occurred.
Please check if any of your loaded .so files has enabled executable stack (see man page execstack(8))

I am trying to get JBoss WildFly 15.0.1 Final to start on a rather small ubuntu 14.04 vServer. The server has only 2 GB of RAM.
I tried to start WildFly many times without success. The JVM seems to require a lot more RAM than I had ever expected.
Here's the console output:
root#t2g55:~# service wildfly start

* WildFly Application Server failed to start within the timeout allowed.

As you can see I specified JAVA_OPTS: -server -Xms768m -Xmx1536m ..., which I thought should suffice for a WildFly server to start. Please not, that the standalone.xml has a datasource defined to a MySQL DB.

QUESTION:
Can this be solved with this amount of memory or do I simply have too few RAM?
What else could I probably try?
I don't really want my provider to go up with the mem successively only to find there's some other problem with Java, the JVM or anything...
Thanks
EDIT 1:
The vServer provider uses OpenVZ for its virtualization.
Info: they just pushed my to 4GB, then once, I got JBoss up and running. After reboot WildFly again refuses to start: same thing, not enough memory (even though I switch between Java 8 and Java 11 runtimes).
CMD to start JBoss WildFly: sh /opt/wildfly/bin/standalone.sh &, standalone.xml appears to be OK. I removed the ExampleDS, three entries commented.
It was indeed a server virtualization issue with OpenVZ.

Hi,
the problem was with the user_beancounters, that is with the privvmpages, these were set too low.

I don't know exactly what he did in detail, but that resolved it.
I now run on a 2GB machine without any problems and memory usage of mysqld + standalone.sh (WildFly + webapp) is around 800 MB.
i am trying to open eclipse but it doesn't response .
it creates a log file automatically (hs_err_pid#no.log).
i tried to download another copy of eclipse but the same problem occur.
