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
java.net.SocketException: Too many open files

Hello rahul kcle,

I have no idea about the java client but this might solve your problem:

add the following line into your /etc/security/limits.conf :

* soft nofile 65535
* hard nofile 65535

reboot your machine and run your program again, see if it works?

Best wishes,
BlueT
