Httpd creating multiple core dumps in Rocky Linux

Hi,

I have migrated from centos7 to rocky linux 9.2. We are using below version of httpd.

Server version: Apache/2.4.48 (Unix)

Httpd keeps creating core dumps multiple times during the day. This is more common if we are running on heavy load but also seen without load and it is random. I have not seen any functional impacts due to this but concerned why so many dumps are being created and any potential impacts due to this. Below are the stacks I have got when the issue is seen. Has anyone faced similar issues? Any pointers on this would be really appreciated as we have not been able to isolate the cause of this.

Not sure what you mean by “migrated”? You are supposed to do clean install.
