*.dmp file in ../cluster/server0 created and growing automatically

[Former Member]

Hello,

we have setu up NW 2004s on Linux. On two instances (J11 and J13) there is a file created in the directory .../cluster/server0 which is called something like that:

core.20090814.055825.15954.0001.dmp

This is growing really fast until the directory has 100 % and the instance crashes. We only see this happening on these two instances (we have other similar servers). Is there a setting on NW which creates these *.dmp files?

Can I shut this file creation off?

Regards,

Kai

That files is created because your instance is crashing, not vice versa.

A core file is a snapshot of a process including its current memory content, so if you java/jlaunch process allocates at the moment it crashes e. g. 2 GB then the file will be as large.

You have to find out the root cause of the crash. So please check the logfiles (dev_server0, std_server0.out, dev_jcontrol etc.)
