    Hello!
    Periodically the following logs are generated on server.
    Code:
    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.

    Could you open a support ticket using the link in my signature so we can take a closer look? You can post the ticket number here so we can update this thread with the outcome.

    Thank you.

    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.

    Hello,

    The reported issue is addressed with internal case CPANEL-6604 as part of cPanel version 58.0.13:

    Fixed case CPANEL-6604: cpsrvd: avoid segfaults when running webmail.

    Information about how to update cPanel/WHM is available on the following document:

    How Can I Update cPanel/WHM?

    Let us know if additional issues continue after updating to this version or newer.

    Thank you.
