Huge laggs starting to occur after 1-2 hours

[nl-saw]

Describe the bug Server running with 3000 bots, when started and all bots have initialized, the DIFF is about 30-45 ms without laggs. This generally stays the same over time but after 1-2 hours (depending on the amount of bots and the inactivity settings) there start to be huge laggs, increasing in both intensity and frequency (up to 6 seconds and beyond!). When you start noticing the issue it becomes exponentially worse, quickly. At that point the game becomes basically unplayable. When lowering the amount of bots, and/or decrease their activeness/increase idling times the problem is just delayed. After a server restart all is fine once again for 1-2 hours and the cycle repeats. Can someone help me with what I can do to help pinpoint the problem? I am not a hardcore developer, but I can manage my way around with some directions.

Commit hash AzerothCore rev. 1294d79764e3 2024-11-25 23:22:31 +0800 (Playerbot branch) (Unix, RelWithDebInfo, Static) (worldserver-daemon)

To Reproduce Steps to reproduce the behavior:

1. Start a server with 3k bots.

Only following mods are enabled:

• mod-autobalance
• mod-dynamic-xp
• mod-rdf-expansion
• mod-solo-lfg

2. Wait (or play) for 1-2 hours
3. Observe insane DIFF times up to 6+ seconds.

Expected behavior There should be no laggs of 1+ seconds happening over time.

Additional context I haven't played around with Playerbots for around a year, so I have 0 clue where this problem might have started for me meanwhile, but this behavior was not happening back then. My server's config files attached. For MySQL I basically just increased the innodb_buffer_pool_size to 32 GB, and I do not see any performance issue with it.

Change mapupdate to 4 in the worldconfig

Not to solve it but works for me. I have some crashes but i belive its cause that it is alot of bots in one city . But can play like 10 hours .

Thanks for that suggestion, with forced 10% i made it past at least 3h. (Stopped to make changes at that point). Will play around with it some more.

I had this problem too, I changed MapUpdate.Threads = 6 just that and I no longer have problems. 4 days running with 3500 bots and I have no problem

innodb_buffer_pool_size to 32 GB

I didn't do that either and had even more problems than a solution.
