Maiman not starting in cPanel server

If the Maiman not starting in cPanel server and getting the following error, it may be bacause of the existing mailman lock files.

Traceback (most recent call last):
File "/usr/local/cpanel/3rdparty/mailman/bin/mailmanctl", line 556, in <module>
main()
File "/usr/local/cpanel/3rdparty/mailman/bin/mailmanctl", line 391, in main
lock = acquire_lock(force)
File "/usr/local/cpanel/3rdparty/mailman/bin/mailmanctl", line 218, in acquire_lock
status = qrunner_state()
File "/usr/local/cpanel/3rdparty/mailman/bin/mailmanctl", line 187, in qrunner_state
os.kill(pid, 0)
OSError: [Errno 1] Operation not permitted

So in order to resolve this issue, move the existing lock file to another directory and restart mailman using the steps mentioned below:

mkdir /root/locks-mailman
mv /usr/local/cpanel/3rdparty/mailman/locks/* /root/locks-mailman/
/scripts/restartsrv_mailman

It should fix the problem!
