Random, Server Crushing Lag (URGENT)
Hello, I have random unexplained lag in my server which happened a few hours ago while the server was running.
I have no idea why they happen
Here are the reports: (see comments)

The server started crashing since then
is it almost exactly every 5 minutes?
if so, that's autosave
Looks like it
I didnt have that issue before
I had it even fixed

server side right?
didnt find anything on it
I am gonna try it now
yeah it is
thank you, I'll update you
didnt work, CPU and RAM use is still maxed out
lots of lag
can I see a new profile then?
Gotta restart server, it wont let me run it
5 min.
Caught this during bootup
maybe its relevant, idk
(final lines after booting)
it might still be fine
im profiling now, cpu use is at 10% which is fine, but after some time it shoots up to 400% (which is my maximum on pebblehost)
it shot up at 400% now after 4 minutes
now I cant end the profiler
I guess I gotta start again

It worked

It just crashed too
maybe try without c2me
c2me hasn't always been the most stable historically
I already tried disabling it before, I will try again

can you do
/spark profiler start --alloc to start the profiler and profile memory allocations (memory pressure) instead of CPU usage.Will do, my bad
oh you're all good, both are useful, but useful for different things
keeps crashing, had to send you the live one, might crash soon.

wait I think I hit it wrong ðŸ˜
its a profile again
/spark profiler start --alloc --timeout 300
Spark Profiler
Spark can be used to see why your server or client is lagging.
Users can share a spark report via
/spark profiler start --timeout 300 which creates a report after 5 minutes. The spark report is useful in debugging why your server is lagging, so ideally you should always provide one while asking for support.

@Snow Kit Considering that this wasnt a problem 2 days ago, do you think I can fix the issue by making a fresh save?
Like, download the map, download player data, wipe the server
then upload them again with the mods
I don't believe so
okay
I will try a 4th time to get the alloc

@Snow Kit the best one I got is this..
it just doesn't seem to add up really
I guess its a mob related issue
I will remove a bunch of modded creatures
the allocations aren't going up enough fast enough
so that's not actually the cause
should I send you my modpack?
You can install https://modrinth.com/mod/radium

thank you very much, though in hindsight I believe I am gonna get rid of sinytra connector and all the other fabric mods.
I am gonna rework my modack and remove most of the modded mobs
that should help I believe
Yeah, probably
