dovecot - Nov 2010 - ioloop.c panic

Timo,

Just this morning I upgraded from 2.0.6 to 2.0.7 (hg changeset
66a523135836). A few hours later we had some power problems that caused
the networking to drop out at one site. The directors on the surviving
site all had a few imap-login processes crash with the following error:

Nov 23 09:15:30 cc-director1 dovecot: imap-login: Panic: file ioloop.c:
line 35 (io_add): assertion failed: (fd >= 0)
Nov 23 09:15:31 cc-director1 dovecot: imap-login: Panic: file ioloop.c:
line 35 (io_add): assertion failed: (fd >= 0)
Nov 23 09:55:48 cc-director1 dovecot: imap-login: Panic: file ioloop.c:
line 35 (io_add): assertion failed: (fd >= 0)
Nov 23 09:55:51 cc-director2 dovecot: imap-login: Panic: file ioloop.c:
line 35 (io_add): assertion failed: (fd >= 0)

I don't have core dumps enabled, so I can't provide any more information
than that. I could enable cores, but I honestly would be hard-pressed to
replicate the network cut-out anyway so I'm not optimistic that any
cores for this message would ever be forthcoming.

Thanks,

-Brad

No other errors besides this? Anyway, possibly this fixes it:
