Too many open Files

[rahul_kcle]

I recently deployed memcached to our production servers and this
exception happened. I am just wondering what might be the reason.  Any
help is appreciated.



We are using  java_memcached-release_2.0.1.jar  client.

Our config is   as following

memcached.pool.initcon=5
memcached.pool.mincon=5
memcached.pool.maxcon=30
memcached.pool.maxidle=1800000
memcached.pool.polltime=5000
memcached.pool.socketto=5000
memcached.pool.conto=0
memcached.value.compthreshold=65536


The following is the exception which resulted in the crash of our
tomcat server.

ERROR com.danga.MemCached.SockIOPool - Too many open files
