/usr/sap/BP1 is getting full after Java resart

[Former Member]

Hello Experts,

When ever we restart our java stack, /usr/sap/BP1 is getting full as "core" file of size upto 3GB is getting created in server0, server1, server2 folders.

Does anyone have idea why this core files are getting generated & how their generation can be stopped?

Regards

Hello Sachin,

The core files are like core.*.dmp?

. core.*.dmp - JVM core dump files create a complete memory dump of the current state of the program when a memory problem occurs.

Hi,

Check thread As per your description, the 3GB dumps suggest memory issues/leaks. Please check the references notes too from the thread.

Also check incase of JVM related dumps.

Thanks Srikishan & Blanca,

Your replies are helpful.

Remove these two JVM parameters using config tool (if they are set):

-XX:+HeapDumpOnOutOfMemoryError

-XX:+HeapDumpOnCtrlBreak

The curious case here is why does it trigger heap dump on restart. Any chance of triggering "Control + Break" signal in the process? which then explains everything.

Kind regards,
