Re: [Moosefs-users] [SPAM] Re: Crashing mfsmaster

Wow, I am sorry, I forgot to get back to the list about this one.

Ok, the devs have informed me that this has been fixed in the upstream code
for the next release, but it was really my fault.

I had set the chunkserver reconnect value to be too low in the
mfschunkserver.cfg files, this was causing the chunkservers to come back too
quickly was causing the mfsmaster to take up %100 cpu spinning it's wheels.

So don't set:
MASTER_TIMEOUT
to anything below 10, and ten is cutting it close, I would stay above 30
unless your install is very small (fewer than 5 chunkservers)
