It's mekanism doing some sort of network maintenance in both cases. The call stack is really quite deep, initially triggered by a te accumulator loading adjacent chunks.

That is what i had found myself. At least i know i was looking at the right stuff.. just didn't see any reference to a TE accumulator.. and not in your screenshot either? (so i had no clue what to look for in my world)

Analyzing them properly is quite tricky, it requires a good amount of knowledge.

Upload a few of the nastier ones (1st number = spike length in ms) and I'll have a quick look.

Here you go, two of the really bad ones:

If it is very clear what the problem is, could you give me some hints as to what i should look for in the future, if this happens again?
I am a professional software engineer, so i'm not completely lost looking at stuff like this, just a bit unsure what numbers i should be looking for and where.

Cheers for the help!

Shinisuryu: This sounds like sporadic lag spikes, take a closer look at /sampler tps, it'll report a max tick time as well, which is the worst recorded for the past ~2 minutes. One cause for this may be when MC writes modified chunks to disk. Sampler's spiketrigger should be able to catch this kind of spikes, run /sampler sampleinterval 3000 and then /sampler spiketrigger 500.

I tried this for my server, since i have been having the same problem with lag spikes on and off a few times.. never really understanding what was causing it...
the spike trigger worked wonders, but i'm at a bit of a loss as to what i should look for in the files.

using VisualVM to look at them atm, but a bit lost in what the different things mean.. What should i look for?

Thanks Player, i'll try that later when i have time to play again.
Will get back to you if it crashes again...

It crashed during play, so may not end up getting the same crash again...

Thanks for this awesome mod Player!

Still need to test more to be sure that it's fixed the lag problems on my server, but so far it looks good.

I did get this error thrown on the client side though: http://pastebin.com/xMP2nxHL
I'll get you a list of mods and versions if you need it.
