Thanks for your reply.
Java is started via a CLP, this is the section that calls it:
ateway.CloudQ') PARM(&DRIVER &INTERNET +
&PRODLIB &CLDFLR &TYPE &ENV &HOSTIP +
&CLDSSL &LOGTYP) CLASSPATH(*ENVVAR) +
CHKPATH(*IGNORE) PROP((java.version &JVM) +
(java.awt.headless true) +
(os400.awt.native true) +
(com.ibm.cacheLocalHost true) +
(java.net.preferIPv4Stack &IP4) +
(java.net.preferIPv6Addresses &IP6)) +
The program runs for several hours or days before the JVM crashes. We have
a 2 gb dump file and also a java core text file which shows all the threat
stack traces etc.
All Java call stacks available show threads to either be in a wait state,
or a sleep state, or a socket read or accept state with the exception of
In case it's any use to you I've uploaded the java core text file to
TLXDRIVER is the user profile that the CL program runs as, which should
belong to *SYSOPR user group and have special authority for *ALLOBJ,
*JOBCTL, *SECADM, *SPLCTL
I will ask the customer to check on authority for QJVACMDSRV *pgm.

How is the java process started, from RPG, RUNJVA, QSH?
Is their any call stack or is it failing right away?
What is the class/method being called?
What authority does the user have that is running the java process, maybe
I would check authority and existence of QJAVA/QJVACMDSRV *pgm.
What is TLXDRIVER? A user profile? Searching for TLXDRIVER I find 2
items related to user profiles.
