OutOfMemoryError : Out of swap space

[Bogdan Dimitriu (bdimitri)]

Are you using any non-JDK libraries that make native calls? If so check
if these don't have an bugs that leak native memory in those areas.

Subject: OutOfMemoryError : Out of swap space

 

Hello,

 

I am intermittently getting the below Out of Memory error for a Java
application running on Windows 2003 with 4 GB RAM. 

 

jvm 2    | 2011/10/03 02:08:00 | #
jvm 2    | 2011/10/03 02:08:00 | # An unexpected error has been detected

Out of swap space?
jvm 2    | 2011/10/03 02:08:00 | #
jvm 2    | 2011/10/03 02:08:00 | #  Internal Error

jvm 2    | 2011/10/03 02:08:00 | #

JDK version: 1.6.0_07

 

JVM settings are: 

 -Xmx16m -Xmx1600m. 

 

Reviewing the bug reports, it seems to have been fixed in jdk 1.6.0_21,
however this is production machine and we don't want to go for an
upgrade presently. 

One of the workaround we came across was to make the -Xms=-Xmx value? Is
there any way to find what value would work for us? 

Please note, that we don't have any other process(s) running on this box
except for the java application. 

 

Thank you.
