I did one more thing: using gdb I attached to all 'imap' processes
and set a breakpoint at the only place in the code where "Unknown
internal error" appears (that is 'index_storage_get_last_error' in
lib-storage/index/index-storage.c) in order to get backtrace for it
(which may or may not help). See for yourselves:

Any thoughts here?
One more piece of info that might (?) be interesting -- I have just
run a grep on historical logs and it seems the bug never occured on
previous versions of Dovecot I had been running in the past (first
it was stock Suse 9.3 Dovecot 0.99.14, then a self-compiled
1.0.rc27).
The only difference (apart from the actual source code, of course)
between 1.0.rc27 and the current 1.0.3 that might play any role are
the configure flags:
- 1.0.rc27: ./configure --with-pam
- 1.0.3 : ./configure --with-ioloop=best --with-ldap --with-sql
--with-mysql --with-pam
This resulted in using epoll() for 1.0.3 and poll() for 1.0.rc27;
both versions are using dnotify.
BTW, 'uname -a' returns:
Linux h648123 2.6.11.4-21.9-default #1 Fri Aug 19 11:58:59 UTC 2005 i686
athlon i386 GNU/Linux
