Maximo "hanging" for 15 minutes

From: Ron Sleijpen (2012-02-02 08:34)

Dear group,

We have a problem with Maximo "hanging" 3 or 4 times a week. It happens
on various times, so there's no structure to recognize.
Suddenly the users get an hourglass and nobody can make any logon to the
system.

Maximo freezes for about 10 to 15 minutes.
When I look in the task manager on the application server, I can see the
JAVA process disappear (go down) and restart itself.
Then Maximo is available again.

We run:
- Maximo 6.2.6 (but we also had it with Maximo 6.2.3 and 6.2.5)
- Websphere 6.0.2.17
- Application server:
o Windows server 2003 SP2 on VMWare
o Java 1.6.0
- Oracle 10G

Since we run on VMWare, IBM will not support our problem.

Is there anybody who had similar problems or any ideas what we can check
or do to tackle this problem?

Many thanks to all in advance.

Have you checked the logs? If the Java process is disappearing, it sounds like you are running out of memory in the heap. What do you have the initial and maximum heap size set to?

Hello,
We had the problem of JVM automatically restarting. This was happening due to memory leaks in the jvm's. It was happening multiple times in a day.
We installed the WAS 6.0.2.25 fixpack in our servers. This resolved our memory leak issues for the most part.
Hope this helps..
Regards,
Ramesh

Hi,
We do a software ripple start of our report/cron server Tuesday and Thursday nights.
We reboot the UI and Report servers Saturday night. This is a full server reboot.
Could be overkill but we have not had issues since we put that in place.
