Can you tell us how you compiled the program, and how you launch it (debug
mode, verbose mode, with a given jvm ...)

Subject: JVM locks up


Hi all,

i have a problem with the JVM on the AS/400.

We develope an programm on an Windows NT System an. On this platform the
programm
executes fine and no problem occured so far.

But if we try to execute the programm on the AS/400 the jvm locks up after
a short period of time.

System: V4R5M0 with the lastest java ptf installed
Java Version : 1.3

The bci job for the jvm could not be accesd through strsrvjob nor through
dmpjvm.

The execution of the dmpjvm command results in the folowing error messages.

 4 > DMPJVM JOB(041952/SMCOREM/QZSHSH)

Sorry that it's in german but our system has the german language installed.

It seems that were is an deadlock if the programm runs on the AS/400 jvm.
But how could you
get information which thread lock up if you could not get an dump of the
threads ???

I will be happy for any suggestions.

Mario

Mit freundlichen Grüßen
