  now this is really strange - after FEW DAYS of load 99% and not being
able to interrupt cleanup (I attached gdb to it and hit ctrl-c) it was
finally interrupted and now it's in:

(gdb) where
#0 0x401f82e4 in open () from /lib/
#1 0x4004354c in rewrite_clnt_stream () from
#2 0x40038151 in mail_stream_file () from
#3 0x0804be05 in dict_changed ()
#4 0x08049a65 in dict_changed ()
#5 0x40027b85 in _init () from /usr/lib/
#6 0x40027ce1 in _init () from /usr/lib/
#7 0x40051e05 in event_loop () from /usr/lib/
#8 0x400286ce in single_server_main () from
#9 0x08049c4e in dict_changed ()
#10 0x4014e14f in __libc_start_main () from /lib/

  I guess that since it's still in open function of libc it was stuck in
open system call?

  any ideas about what's going on?
