Обсуждение: Segmentation fault

Hi all.
I got “terminated by signal 11, segmentation falt” error in my database.
I’m using pg v13.7
Query causing that error: “set client_encoding= utf-8”
There is no core file in data folder.
Any idea how can I find the root case for this error?
Command execute for 1000times, but only some times cuz this error

Regards

Hmm, that is pretty well-tested code.

Maybe you are starting the server under "ulimit -c 0"?  See also

With only this amount of information, there's not much to be done.
If you could get a stack trace maybe we'd have some ideas.
