[emerg] (28)No space left on device: Couldn't create accept lock


1) There is huge session problem. Some
time all start working well and some time no body able to login.
Apparently session variable stop working.

Error:  Within the Apache error logs, this message appeared over and over:

[emerg] (28)No space left on device: Couldn't create accept lock

command to see semaphores,

Added the below lines in /etc/sysctl.conf
Increased Apache Semaphore value system wide
kernel.msgmni = 15727
kernel.sem = 250 256000 32 1024

2). Open file limits error.

 Modified fs.file-max=200000 in /etc/sysctl.conf
