Subject tomcat5.0.28 out of memory for swap space was not released!
Date Tue, 25 Sep 2007 05:37:13 GMT
I am a Chinese and English is not well,but I will try my best to express myself.
I have HP-UX operation system with JDK1.5 and sybase.But after tomcat5.0.28 running for some
times ,it would out of memory.The tomcat5.0.28 process continuously allocated swap space but
not released it.So when swap space was insufficient,tomat5.0.28 out of memory and shutdown!
Below is some information:
tomcat startup script parameters: JAVA_OPTS="-Xms1001m -Xmx1001m -XX:MaxPermSize=800m -Dfile.encoding=GBK"
out of memory log in cataline.out:
2007-08-29 17:38:07.283 (] DEBUG - render Id = pagination 
 Exception java.lang.OutOfMemoryError: requested 74856 bytes for GrET* in /CLO/Components/JAVA_HOTSPOT/Src/src/share/vm/utilities/growableArray.cpp.
Out of swap space?
Possible causes:
    - not enough swap space left, or
    - kernel parameter MAXDSIZ is very small.
