    Was the server rebooted?

    Was the notice seen near the same time as when you performed the update (shortly before, during, or shortly after it finished)?

    Did the services automatically restart successfully?

    If you're experiencing a large number of services frequently failing I recommend escalating the issue via a ticket; there may be any number of causes that can only be determined by investigating the system directly.

    hello Don, well, i update cpanel.

    no, i dont restart the server.


    the failing servers start like 10-15 min after update ended.


    yes, everything now looks good, for example, right now 11 pm, no services are failing. since 6pm everything looks good, let see if tomorrow during the day, services stay up.

    thanks

    While this may not directly alleviate the entire issue, I would consider ensuring the operating system (OS) is updated to the latest available release. The existing version of CentOS 5.2 could be upgraded to CentOS 5.4 that is currently available. The following command will accomplish this task via root SSH access:
    Code:
    # yum upgrade
    To verify the OS version after updating the following command may be used:
    Code:
    # cat /etc/*release
    Is the system a VPS or in some form of a virtual environment (e.g., Virtuozzo/OpenVZ, Xen)?

    The following command will help determine the above:
    Code:
    # cat /var/cpanel/envtype && echo
    If it is Virtuozzo or OpenVZ, please check the following for the "failure count" information (in the last column of data):
    Code:
    # cat /proc/user_beancounters
    If the same symptoms persist, due to the nature of the issue, where multiple services are repeatedly failing (or at least being reported as having failed), I recommend escalating the issue via a ticket. I may suggest checking first with your upstream data center as they can physically check and access the machine directly (including for hardware diagnostic testing). If submitting a support request to cPanel, please send me your ticket ID number so that I may follow-up internally and verify the circumstances involved; if appropriate I can then share the solution in your forums thread.

    no servers failing, what i do???

    modify the vps conf, the QUOTAUGIDLIMIT="380"

    was 320, and i change the limit to 380 and the accounts transfers work, and the servers no fail for today.

    but here is the paste of the beancounters.

    what is QUOTAUGIDLIMIT, i search google and in a post i see:

    "quotaugidlimit is used to track the numer of group and users with quotas. As you add more users and groups it gets near the limit"

    sounds reazonable for me, that was my problem and that cause the server been restarting the services...


    thanks Don

    Thank you for the detailed update and information. The specified parameter is used by Virtuozzo and OpenVZ; for more verbose detail please reference the following documentation:
    KB Parallels: What is the difference between 'disk quota' and 'hard disk quota'?
    KB Parallels: How do I solve this problem: edquota: "Can't write quota for /dev/vzfs"?

    Does the file "user_beancounters" (for Virtuozzo/OpenVZ) still show a failure count for any of the listed parameters?

    Are there any errors in the log files for the affected services?
