java.io.IOException: Too many open files #237

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
OS: Linux
I am getting following exception when connecting to Memcached server. I did 
some local test in which I created 200/300 threads and I started getting 
connection errors, any idea?

Please don't use the bug system for questions.

Chances are you need to set the limit on open file descriptors higher for the 
user/process.  If you have further questions, please send an email to the 
mailing list.

Thanks for the response, I have posted this in mailing list as well. I add it 
here coz I saw lots of failure in multithreaded environment. I get timeouts, 
connection error.

I am also getting the following errors - I know this should be in different 
thread, I have also posted this in mailing list pending approval.
