java.lang.OutOfMemoryError

[GnanaShekar]

Hi,

A user here is getting the following error while running weblogic.

Exception in thread "CompilerThread0" java.lang.OutOfMemoryError: requested 42644 bytes for Chunk::new. Out of swap space?
Possible causes:
- not enough swap space left, or
- kernel parameter MAXDSIZ is very small.
Java out of memory messages are marked with pid: 24270 in /var/adm/syslog/syslog.log.

Following are the details of swap space and physical memory.

Please suggest,

Are there any memory management options added to the Java virtual machine startup command (in startup scripts of Weblogic)?

The -Xmx option might be the most interesting: it specifies the size of Java memory allocation pool. The default size is 64MB, which can be too small for large Java applications.

If this setting is too small, you might get Java "out of memory" errors regardless of the amount of the real memory.
