Yes it means the pop3 script was already running, when it tried to launch it again.  In my case this is the PostMasterPOP3.pl script.  Look for it in the process table and kill it.

ps -ef | grep -i pop

kill PID  (the PID may be 17058)

If the error message continues you may need to increase the interval between checks, or you may have to figure out if you have a problem with the account… like a large email or a problem with login credentials.

Has anyone else seen this error? OTRS refuses to download email from the POP server.

Can't create PID PostMasterPOP3, because it's already running (server.domain.mil/17058)!
