I never said Java would exceed the maximum heap memory limit while being idle.
Note that you can monitor the Java heap memory limit being used by using system tools. -------------------------------------------------------------- Sharon Lucas IBM Austin, luc...@us.ibm.com (512) 286-7313 or Tieline 363-7313 Strösser, Bodo <bodo.stroes...@ts.fujitsu.com> 07/27/2009 05:59 AM To Sharon Lucas/Austin/i...@ibmus cc "'staf-users@lists.sourceforge.net'" <staf-users@lists.sourceforge.net> Subject RE: [staf-users] STAX-Service gives RC: 6 Sharon, up to now I didn't change the memory setting. So "-Xmx384m" was in use. I changed "ulimit -c" settings to "unlimited" and tried again. No core and no Javacore files are created when java exits. Next is to test using "-Xmx1024m". But I think, this is not very likely to be the reason, as java normally exits in the night or at the weekend, while nothing is running on STAF/STAX. Why should java exceed the limit while being idle? I would expect problems when running big jobs.

Did you look to see if a system core file (e.g. with filename core* or core*.dmp) was created (probably in the directly from which STAFProc was started) and/or a javacore*.txt file was created when the JVM crashed. Javacore*.txt files are readable text files containing thread dumps. Note that these files get created when a JVM crashed (depending on the system's configuration) and that that these files tend to be quite large, depending on the JVM's heap settings.. Did you increase the maximum heap size when you configured the STAX service? If not, you should try increasing it in case the JVM ran out of memory. For example, the following sets the maximum heap size for the JVM that the STAX service runs in to 1024m: SERVICE STAX LIBRARY JSTAF EXECUTE {STAF/Config/STAFRoot}\lib\STAX.jar \ OPTION JVMName=STAX OPTION J2=-Xmx1024m You can also enable JVM debugging options if you wanted using the the J2 option when configuring the STAX service. Note that the information in the STAFProc console are errors that occur when you submit a request to a STAF Java service that is running in the JVM that as crashed. -------------------------------------------------------------- Sharon Lucas IBM Austin, luc...@us.ibm.com (512) 286-7313 or Tieline 363-7313 Strösser, Bodo <bodo.stroes...@ts.fujitsu.com> 07/22/2009 11:47 AM To "'staf-users@lists.sourceforge.net'" <staf-users@lists.sourceforge.net> cc Subject [staf-users] STAX-Service gives RC: 6 Hi, yesterday I installed and started STAF/STAX (3.3.4 / 3.3.7) on a Linux 32bit. Java is Sun 1.6.0_14. After a few hours, STAX does no longer work: # staf local service list Response -------- Name Library Executable --------- ---------- ------------------------------------------- DELAY <Internal> <None> DIAG <Internal> <None> ECHO <Internal> <None> EVENT JSTAF /usr/local/staf/services/stax/STAFEvent.jar FS <Internal> <None> HANDLE <Internal> <None> HELP <Internal> <None> LIFECYCLE <Internal> <None> LOG STAFLog <None> MISC <Internal> <None> MONITOR STAFMon <None> PING <Internal> <None> PROCESS <Internal> <None> QUEUE <Internal> <None> SEM <Internal> <None> SERVICE <Internal> <None> SHUTDOWN <Internal> <None> STAX JSTAF /usr/local/staf/services/stax/STAX.jar TRACE <Internal> <None> TRUST <Internal> <None> VAR <Internal> <None> # staf local stax help Error submitting request, RC: 6 When doing "ps -ef | grep -i staf", the JVM is gone. /usr/local/staf/data/STAF/lang/java/jvm/STAFJVM1/JVMLog.1 doesn't contain any error messages. Maybe, there is a problem regarding this JRE, as another Machine running the same STAF/STAX, but Java 1.6.0_12 doesn't show this problem. But it is another linux version also. What can I do to get debug info?
