Title:
Server has massive lag all of a sudden
Launcher Version:
1.7.10
Modpack:
FTB: Infinity
Modpack Version:
Log Link:
Details of the issue:
I run a FTB: infinity server, and last night while me and my friend were searching for coven witches, we we ran into huge lag spikes, where chunks would take many seconds to load. (Additionally, the server was posting the "trying to keep up" warning) To the point where the server itself crashed. I restarted the server, and it still had massive lag and chunk loading errors. I then went into the server start, changed the Memory to 4GB (down from 5 as I heard that sometimes helps) and now its better, but only slightly. The used memory is only at 30% (Allocated at 96%).

Im not sure what caused the issue in the first place. I have read that Mystcraft can cause an issue sometimes, but no one on the server has even started a Mystcraft age. Does anyone have any other advice or similar experiences that might be able to help?
