Segfault at libperl.so

[Rakaris Bakaris]

Hello!
Periodically the following logs are generated on server.

Jul 22 11:05:18 websever kernel: [1546945.460606] webmaild - serv[8073]: segfault at c ip 00007fd1dca1ffdb sp 00007ffdf658d380 error 4 in libperl.so[7fd1dc9c8000+17e000]

How to resolve this or can I ignore this?

Server OS: CentOS release 6.8 (Final) / x86_64
WHM 56.0 (build 28)

Thanks!

Hello,

Are you encountering any additional issues on the system? I suggest reaching out to your data center or hosting provider to have them verify there are no hardware issues on your system (e.g. bad RAM).

Thank you.

Not. I have not got any other issues.
I think that this is not hardware related. I had the same events on old server on other data center. The server is not online for a time, so I can't show live system.
I was able to reproduce the issue with root user by opening some account's webmail for first time after root is logged in.

Was there a solution to this? I see this message on several servers. Maybe it is related to somone attacking the webmail service (DOS). I usually see higher loads when this happens.

Hi,

I have noticed the same error with Cpanel RELEASE 11.62.0.17. Is the same issue again reported with 11.62 ?
