Server freezes for some time after some minutes

  • My server has been running very weirdly as of recent.

    It used to run well with minor lag and freezes, but the last month we've tried everything to fix the issues.

    We got to a point where everything ran normally for 5 seconds, then froze, then normal again. For 5 seconds each. Then after 5 minutes it crashed.

    We managed to fix that by removing a client mod that seemed to be causing issues.

    After that we kept on playing but realised combat was unplayable. Our current situation is:

    * Mobs freeze for 2 seconds then move at the speed of sound for the next 2 and cycle between that.

    * The entire server freezes for 40 seconds then unfreezes and executes everything we did during those 40 seconds in a single second. Making combat even further impossible, specially in boss fights.


    We have a very high amount of mods and tried removing some but it just causes more issues. So I wanted to ask if maybe we're doing something wrong and if there's a setting or something that causes this or if it will go away in the future or something?

    Here is a list of our mods, its quite big, if one is conflictive I'll appreciate you telling me, even though we can realistically only remove ars_noveau, I'd still like to know if any other causes extreme lag. This is a one year project for people we love and we would be devastated having to delete it or abandon it because of lag.
