Fatal error: word too long

[Erik Steffl]

  I got the following error:

Jul 17 08:51:48 jojda cyrus/imapd[7560]: open: user erik opened In.~ SPAM ~
Jul 17 08:51:50 jojda cyrus/imapd[7878]: Fatal error: word too long
Jul 17 08:51:50 jojda cyrus/master[301]: process 7878 exited, status 75

Jul 17 08:53:43 jojda cyrus/imaps[7908]: executed
Jul 17 08:53:43 jojda cyrus/imapd[7908]: accepted connection

  any ideas about what does it mean?

  I also got some other errors, not sure if they are related (Could not 
shut down filedescriptor 0: Bad file descriptor) but from MUA (Mozilla) 
it all looks ok - mail is being delivered (not sure if every single 
email is delivered), marked seen etc.

  TIA
