multiple consistant crashes on multiplayer vanilla server

on multiplayer survival vanilla server since 15w49a the server has multiple consistant lag and server crashes for everyone, it is extreme and nonstop, i even tested by going to a unloaded chunk with no one else on server away from anything and same thing, server periodicly consistantly crashes, this is also reported to happen when i am not on so it is not my graphics drivers. it is bad.

as of release of 15w50a it has not changed, still happening

Please attach the server's crash report / log file.

I haven't experienced any server crashes in 15w50a, but I have in 15w49b. 47c didn't have that problem at all.

The spikes send to stem from increasingly CPU and RAM usage. This is on a dedicated Linux host running Java 8, not locally. The spikes keep increasing and increasing until at one point, the server doesn't respond anymore, requiring a restart.

I have no evidence, but the symptoms look to me like a very bad memory leak. RAM gets saturated and improperly cleaned up. At one point all the CPU does is run the Java garbage collector and the server process grinds to a crawl. My bet is if I'd let it run longer it would eventually stop all by itself.

I simply restart the server whenever it becomes unplayable, usually after 4-5 hours, when all alone, and after 45 to 60 minutes when we're 2. With 3 players, it becomes unplayable after only 5 to 10 minutes.

I'm surprise to not find any related/duplicate about this one. I'm surely not an isolated case!

It would help a lot if devs would include a TPS meter (showing TPS server-side) in the debug screen.

Ticket resolved as incomplete, because no answer in a reasonable amount of time (1+ year), if it still happens, please update the ticket.
