thanks for the reply IgorG,
But we are using the 9.5.4 version of plesk that is running linux, so our configuration file name is "plesk.conf" in /etc/sw-cp-server/applications.d directory.When i change these values as related to solution link, plesk doesn't start and getting failed message.

Also i am seeing four values in plesk.conf file unlike 2 values.

egrep 'max-procs|min-procs' /etc/sw-cp-server/applications.d/plesk.conf
"max-procs" => 1,
"min-procs" => 0,
"max-procs" => 1,
"min-procs" => 0,

which can i change values in these lines to resolve processing problem ?
Any suggestions would be greatly appreciated.

IgorG,

today I had an issue with starting qmail, /usr/local/psa/var/log/maillog told me that too many files were opened.
Grepping on the lsof output, I found that sw-engine-cgi had over 23000 files open.

So I killed all instances, and started Plesk again.

Issue still existed, so I took the guideline of ugurcane and opened up /etc/sw-cp-server/applications.d/plesk.conf
We had seen this issue before, and my colleague had changed the min-procs to 1 in /etc/sw-cp-server/applications.d/plesk.socket.sh
Applying the same fix to /etc/sw-cp-server/applications.d/plesk.conf did the trick for us.


A side note, we have only experienced this with Xen VM's running CloudLinux 5.
