I'm getting error messages on Eclipse (Mac):
Invalid maximum heap size: -Xmx5120m-Djavax.net.ssl.trustStore=/usr/local/keystore/JavaKeyStore.jks-Djavax.net.ssl.trustStorePassword=changeit-Dtls.key.store=/usr/local/keystore/JavaKeyStore.jks-Dtls.trusted.store=/usr/local/keystore/JavaKeyStore.jks-Dawsmock.directory=/ijmeang/elis/s3-mock-Dcatalina.base=/usr/local/workspace/workspace-eclipse/.metadata/.plugins/org.eclipse.wst.server.core/tmp0-Dcatalina.home=/Library/Tomcat-Dwtp.deploy=/usr/local/workspace/workspace-eclipse/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps-Djava.endorsed.dirs=/Library/Tomcat/endorsed
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
How can I fix this?
Here are the arguments on Eclipse:
-Dcatalina.base="/usr/local/workspace/workspace-eclipse/.metadata/.plugins/org.eclipse.wst.server.core/tmp0" -Dcatalina.home="/usr/local/Tomcat-7.0.6.9" -Dwtp.deploy="/usr/local/workspace/workspace-eclipse/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps" -Djava.endorsed.dirs="/usr/local/Tomcat-7.0.6.9/endorsed" -Xss768m -Xmx5120m -XX:MaxPermSize=5120m -DmasterPropertiesLinux
I would suggest trying to decrease your value of -Xmx5120m, as described here:
https://wiki.eclipse.org/FAQ_How_do_I_increase_the_heap_size_available_to_Eclipse%3F
Some JVMs put restrictions on the total amount of memory available on the heap.
It depends on what Java are you using. If you are using 32 bit Java you may not be able to use more than 2GB.

I am getting the error "Uncaught Exception java.lang.stack overflow error null in Jmeter while performing only one thread. Initially, all requests passed, when I try to click on 11th request to see the HTML response type it starts throwing errors. Since that page contains more images with search functionality
You can run the Java VM with a larger stack size by applying a flag like -Xss1024k. From what I found, the default is 1024k (1 MB).
For example:
$ java -Xss2048k -jar myfile.jar
or
$ java -Xss256m -jar myfile.jar
The alternative is to optimize your code. However,
Premature optimization is the root of all evil.

I recently reinstalled Netbeans IDE on my Windows 10 PC in order to restore some unrelated configurations. When I tried checking for new plugins in order to be able to download the Sakila sample database,
I get this error.
I've tested the connection on both No Proxy and Use Proxy Settings, and both connection tests seem to end succesfully.
I have allowed Netbeans through my firewall, but this has changed nothing either.
I haven't touched my proxy configuration, so it's on default (autodetect). Switching the autodetect off doesn't change anything, either, no matter what proxy config i have on Netbeans.
Here's part of my log file that might be helpful:

It might be that the update server is down just right now; i haven't been able to test this either. But it also might be something wrong with my configurations. I'm going crazy!!1!
Something that worked for me was changing the "http:" to "https:" in the update urls.
I.E. Change "http://updates.netbeans.org/netbeans/updates/8.0.2/uc/final/distribution/catalog.xml.gz"
to "https://updates.netbeans.org/netbeans/updates/8.0.2/uc/final/distribution/catalog.xml.gz"
No idea why that makes it work on my end. I'm running Linux Mint 19.1.
For google certification , we need to run Compatibility test suite on the android device(stb) .
I have done the setup for CTS on a Linux machine.
I am getting below error while running cts-tradefed on the machine.
./android-cts/tools/cts-tradefed
Invalid maximum heap size: -Xmx4g
The specified size exceeds the maximum representable size.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Can anyone give the solution for it?
Just open android-cts-[X.X]_[rX]-linux_x86-arm/android-cts/tools/cts-tradefed from any text editor and change line number 131 $RDBG_FLAG -Xmx4g with any memory size which is less than your RAM size e.g. Xmx3g
Also check if you are using Linux 64Bit version. This issue might occur if you are using 32Bit(which is not supported)
We are running on 32bit windows and since upgrading from 1.4.1 to 2.2.2, we are seeing the following memory in stdout (numbers not exact):
INFO: Database 'BLAH' uses 770MB/912MB of DISKCACHE memory, while Heap is not completely used (usedHeap=123MB maxHeap=512MB). To improve performance set maxHeap to 124MB and DISKCACHE to 1296MB
With 32bit, we can only set a max of Xmx + storage.diskCache.bufferSize ~= 1.4gb without getting OOM or performance issues. Any combination of different sizes of either of these two configurable variables results in a variant of the above message.
Is there a way to suppress the above profiler/memory checker messages?
You can disable the profiler with:
java ... -Dprofiler.enabled=false ...
Set that configuration in your server.sh or in the last section of config/orientdb-server-config.xml file.
I installed OrientDB 2.2.0 on my server but can't start it running server.sh script. Previous version started fine on the server and the current version is running on my notebook. The server is a droplet from Digital Ocean with Ubuntu 15.10 32-bit. The error I get is below.
Invalid maximum direct memory size: -XX:MaxDirectMemorySize=512g The
specified size exceeds the maximum representable size. Error: Could
not create the Java Virtual Machine. Error: A fatal exception has
occurred. Program will exit.
Update
The problem was with -XX:MaxDirectMemorySize=512g. I changed it to -XX:MaxDirectMemorySize=512m and the error disappeared. The problem now is that the server tries to start but gives me the message below:

(Posted on behalf of the OP).
Everything is okay now. I just changed -XX:MaxDirectMemorySize=512m to -XX:MaxDirectMemorySize=2g.
I suppose you have 32-bit JVM. You should set this value to -XX:MaxDirectMemorySize=2g .
