OpenJDK 64-Bit Server VM Insufficient Shared Memory Error: How to Fix

This warning message indicates that the OpenJDK 64-Bit Server VM is unable to allocate sufficient space for a shared memory file. This can occur when the default temporary directory used by Java is not large enough or has run out of space.

To resolve this issue, you can try using the -Djava.io.tmpdir= option to select an alternate temporary location with more available space. For example, you could set the temporary directory to a different drive or partition that has more free space available.

To do this, add the following command line argument when running your Java application:

java -Djava.io.tmpdir='/path/to/temp/dir' MyApp

Replace '/path/to/temp/dir' with the path to the directory you want to use as the new temporary location.

By specifying a larger or more available temporary directory, you can prevent the shared memory file from running out of space and avoid the warning message.
