exhausted memory isn't going to cause it to pause...

Or maybe its like you have exhausted your memory. Can you please check in
the stats if there is any "eviction_count"? This problem will also get
solved once the memcache is restarted.

Hi, 

thanks for the answers. We will try to upgrade. Yes, it does not work just 
to flush the memcached we have to restart them so maybe its 
the persistent connections

Maybe you're just running out of persistent connections... Have you tried 
restarting other servers, instead?

What version are you using? If less than 1.4.17, please upgrade to the
latest version.

Also, -t 25 is a huge waste. Use -t 4 unless you're doing more than
several hundred thousand requests per second.

Memcached somhow hangs or stoppes working

2014-04-14 Thread Jon Hauksson
Hi,

I work at company where we use memcached and suddenly it stoppes working 
every like 3 days. We did not really catch the problem at first but now we 
have narrowed it down to memcached. Every time we restart our 2 memcached 
servers the system gets under control again. But when this happens we do 
not see any real problems in the logs etc...but it comes back after restart 
of the memcached. It does not work to just flush. If somebody has some 
information on what the problem could be it would be appreciated.

We have 2 memcached servers on cent os and the startup options are:

memcached -d -m 4096 -c 4096 -t 25

Thanks,
Jon
