How to handle core-dumps and crash dumps

Jump to solution

Hi Community,

I lately got in touch with the wonderful ccc tool and noticed, that in some environments I got notified, that core dumps or crash dumps are present.

I figured out, that the core dumps are produced by the individual Check Point processes, if anything bad happens and the are stored at /var/log/dump/usermode.

Can anyone explain what the Crash dumps mean and where they are stored?

Is there a procedure I should execute after finding a dump? Contacting TAC? Analyzing the files? Are there special tools for it?

Looking forward to your feedbacks

Best Regards
Johannes

Generally speaking, a core file means "something crashed."
Individual processes crashing will create a core file, as will a system panic, which will generate a kernel dump.
Analyzing such files generally requires unstripped binaries/libraries, the tool gdb, and knowledge of what to look for.
If you're seeing undesired behavior along with core files, best to engage with the TAC.
Note that cpinfo actually collects these core files by default.
