Minecraft sudden lag and freeze

I have been experiencing sudden lag, followed by freezing in less than 3 seconds, while playing, usually 15-30 min into gameplay.
It is really irritating, as it doesnt even recover with a REISUB
java version "1.7.0_67"
Java(TM) SE Runtime Environment (build 1.7.0_67-b01)
Java HotSpot(TM) 64-Bit Server VM (build 24.65-b04, mixed mode
Core i3 -3220 with 4Gb ram

It otherwise gives about 56-60 fps while playing.

I have a feeling (based on vague studies on logs) that it has something to do with disk syncing. I further think this is the case as when I loose power (very often here in hyderabad), my game save is very rarely lost, but with the freeze, it happens 50% of the time.

Only way to recover is to physically reboot.

I allocate -Xms2G and -Xmx3G

I will post results after deleting the flags/updating java

UPDATE:

Linux 3.16.2-1

Yell at me if I forgot anything

If it is not recovering with REISUB (assuming you have sysreq enabled) that suggests something serious. I would first try to rule out hardware problems. Check dmesg, journalctl, test your memory, use smartctl to at least run an extended test on your disk(s) [consider using badblocks to do a non destructive test as well]. Are you using anything special for a file system such as btrfs, RAID, or some sort of networked drive?

I will do the tests, but I have btrfs on my root. I use ext4 for /home. Minecraft resides in /home.
I have all the sysreqs enabled.
I have switched to openjdk, and removed the memory flags. Now I get only 35-40 fps, but no crashing.

Are you playing Minecraft 1.8? If so, thats the problem.
