[Dovecot] imap daemon consuming all the cpu

[Rui Lopes]

Hello,

I've tried to do a full text search on the inbox, it run fine, but the 
imap daemon started to eat all the CPU until I closed the email client.

I'm running dovecot 1.0.rc7 [using kqueue] on FreeBSD 6.1.

ktrace shows this pattern over and over (its seems to be looping):

  49021 imap     CALL  kevent(0x4,0,0,0x80df000,0x5,0xbfbfe988)
  49021 imap     RET   kevent 1
  49021 imap     CALL  gettimeofday(0x80d0b00,0x80d0b08)
  49021 imap     RET   gettimeofday 0
  49021 imap     CALL  gettimeofday(0x80d0b00,0x80d0b08)
  49021 imap     RET   gettimeofday 0
  49021 imap     CALL  kevent(0x5,0,0,0xbfbfe930,0x1,0xbfbfe928)
  49021 imap     RET   kevent 1
  49021 imap     CALL  gettimeofday(0xbfbfe990,0)
  49021 imap     RET   gettimeofday 0

Maybe this is useless to track the cause... :(

Unfortunately(?) I can't reproduce this again, because searches run OK.


Best regards,
