Java server process fails with OutOfMemory error

Christian Hiller_1 — Tue, 23 Nov 2004 02:00:54 GMT

Hello,

we are running an ERP-System based on a java server. Now, we have the problem that the server terminates sometime with the error message:

Exception in thread "CompileThread0" java.lang.OutOfMemoryError: requested 74286

0 bytes

Possible causes:
- not enough swap space left, or
- kernel parameter MAXDSIZ is very small.
JVM Starter by LDS ver. 2.8.4 Sep 1 2003

The server process is running with the following java parameters:

-XX:MaxPermSize=110m
-Xms256m
-Xmx768m
-DORBgcTimeout=86400

The java version is:

java version "1.3.1.12"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1.12-031205-12:07)
Java HotSpot(TM) Server VM (build 1.3.1 1.3.1.12-_05_dec_2003_13_05 PA2.0, mixed mode)

System hpux 11.11 (PA_RISC)/ Goldbase Dec 02, model 9000/800/rp7410.

The machine has 8 GB physical RAM and 4 GB swap space. The MAXDSIZ is set to 1825361100.

Does someone know why the server process aborts sometime?

Christian

Hi Christian,

8 GB of RAM and 4 GB of swap space?. I assume you enabled 'swapmem_on' kernel parameter. If it is only 4 GB swap means, you can only bring up 4 GB worth processes. Post your 'swapinfo -t' output. I believe you may be running out of swap.

We have a java based system that received out of memory errors on install. It did not gives us the out of swap space message or MAXDSIZ parameter may be too small that you are recieving, so our fix may be completely different but we ended up having to increase the max_thread_proc kernel parameter. Hope that helps.
