    In reference to thread:
    Backup crashed server / audit: backlog limit exceeded

    I just had the same issue on our dedicated servers. That solution helped me with those nasty freezes!
    Is there actually any need for audit? Are there anyone using it on hosting servers? This is default "on" on new RHEL systems today.

    I was experiencing the same issue two days ago, I thought it was caused by R1soft because the server no responding just a few mins after R1soft replication started. I saw the backlog limit exceeded message in the server console. The server is cloudlinux 7.

    Yes, especially on Cloudlinux 7.x and when R1Soft was running the server crashed all the time.
    We also changed the audit/backlog limit to 16.000 or something, but didn't help much.

    Do you see log like this on your server?

    /var/log/messages
    Jan 29 22:07:20 xxxx kernel: blk_update_request: I/O error, dev fd0, sector 0
    Jan 29 22:07:20 xxxx kernel: blk_update_request: I/O error, dev fd0, sector 0
    If yes, it's probability related to floppy device. When R1soft runs, it generates the above error on server. I only see this error on cloudlinux 7. I disabled it by this command:

    # rmmod floppy
    check floppy mod is loaded or not

    # lsmod|grep floppy
    floppy 69417 0
    If you reboot the server, the floppy module will be back. I've tried to disable it by this but it didn't work.

    /etc/dracut.conf.d/nofloppy.conf
    omit_drivers+="floppy"

    and

    /etc/modprobe.d/nofloppy.conf
    blacklist floppy​
