I'm having a server. The server information I've given below.
Linux host.com 2.6.32-531.29.2.lve1.3.11.1.el6.x86_64 #1 SMP Thu Dec 18 06:49:17 EST 2014 x86_64 x86_64 x86_64 GNU/Linux
When I was trying to restart Dovecot IMAP and POP. It got failed and showing following error.
Jul 23 01:30:41 platinum dovecot: imap-login: Fatal: master: service(imap-login): child 747903 returned error 127
Jul 23 01:30:41 platinum dovecot: pop3-login: Fatal: master: service(pop3-login): child 747902 returned error 127

Jul 23 01:30:39 platinum dovecot: master: Warning: /selinux is no longer mounted. See http://wiki2.dovecot.org/Mountpoints
I've read some manual, tried to ignore this mounted file. However it is still not working. May i know how I can solve this issue ?
After manual restart following is logs
