Regular coredumps of 1.0.1.1 and 2.0.M2.D1

Hello all,

I have bigger problems with RTC. I am trying to host the jazz-server online.
Now I am getting regularly a core-dump of the servers.

Is there any way to determine why the coredumps occur?
Isn't is a good idea to host the jazz online?

best regards,
Hans

Running the server online should not affect the stability of it! We host our development at jazz.net.

Can you provide information about your configuration including the JRE details?

Hello acho,

I am running the current RTC 2.0 and the RTC 1.0.1.1 with the shipped ibm-jdk.
I have today switched the RTC2 to the sun-jdk and I am awaiting the results.

The platform:
- intel
- vmware-Server virtualized system
- ubuntu 8.04 LTS x64

I have increased the trace-level in log4j to INFO. Maybe I will get more info about the issue.

regards

Hello hkais and acho,

I have a similar setup. I am running under ubuntu 8.04 LTS 64 Bit.
I have also the problems, that my Jazz-VM (ibm and sun) are exiting with coredumps. I am currently running again on 32 bit to verify if it is a 64 bit problem...

bye
Darko
