Hi,3 days ago i noticed i started getting messages from cron daemon on my OTRS box of the form:- Malformed UTF-8 character (unexpected continuation byte 0xa9, with no preceding start byte) in substitution iterator at /opt/otrs/Kernel/System/EmailParser.pm line 655, <PRODUCT> line 4. Malformed UTF-8 character (unexpected continuation byte 0xa9, with no preceding start byte) in substitution iterator at /opt/otrs/Kernel/System/EmailParser.pm line 655, <PRODUCT> line 4. Malformed UTF-8 character (unexpected continuation byte 0xa9, with no preceding start byte) in substitution (s///) at /opt/otrs/Kernel/System/EmailParser.pm line 669, <PRODUCT> line 4. Malformed UTF-8 character (unexpected continuation byte 0xa9, with no preceding start byte) in substitution (s///) at /opt/otrs/Kernel/System/EmailParser.pm line 670, <PRODUCT> line 4.

Malformed UTF-8 character (unexpected continuation byte 0xa9, with no preceding start byte) in substitution (s///) at /opt/otrs/Kernel/System/EmailParser.pm line 675, etc etc Since this time I am receiving no notifications from OTRS and no tickets are being created. I checked /var/log/messages and noticed at the time I started getting these reports from cron, the log was showing:- May 19 19:30:05 rt3 OTRS-PM3-30[14784]: [Notice][Kernel::System::PID::PIDCreate] Can't create PID PostMasterPOP3, because it's already running (rt3.blah.local/14612) ! And every so often I get:- May 20 10:30:04 rt3 OTRS-PM3-30[30434]: [Notice][Kernel::System::PID::PIDCreate] Removed PID (PostMasterPOP3/rt3.blah.local/29415, because 1 hour old! May 20 10:40:05 rt3 OTRS-PM3-30[30620]: [Notice][Kernel::System::PID::PIDCreate] Can't create PID PostMasterPOP3, because it's already running (rt3.blah.local/30434) I'm running otrs 2.1.7 Any pointers as what might have gone wrong? Thanks Mike
