Hello,

Have a bit of a problem with Exim 4.12 + exiscan-4.12-25.
I started using Exim about 3 weeks ago, liked it a lot, and till yesterday
everything worked ok. But yesterday and today Exim started to die
occasionally on signal 11. Like this:

Mar 30 11:12:16 cloud /kernel: pid 21664 (exim-4.12-1), uid 26: exited on signal 11
Mar 30 11:49:16 cloud /kernel: pid 22225 (exim-4.12-1), uid 26: exited on signal 11
Mar 30 13:02:08 cloud /kernel: pid 23459 (exim-4.12-1), uid 26: exited on signal 11
Mar 30 20:52:47 cloud /kernel: pid 912 (exim-4.12-1), uid 26: exited on signal 11
Mar 30 21:38:58 cloud /kernel: pid 1632 (exim-4.12-1), uid 26: exited on signal 11
Mar 30 23:30:04 cloud /kernel: pid 3409 (exim-4.12-1), uid 26: exited on signal 11

The latest of these events I managed to document in the "-d+all" mode by
running listening daemon like this:

2710  p1  S      0:01.37 /usr/local/sbin/exim -d+all -bd -q10m  (exim-4.12-1)


The relevant part of the debug log seems to suggest there is something
wrong with ident code:
...
23:28:35  2710 Listening...
23:30:04  2710 ---0 Get 614688     0       daemon.c  164
23:30:04  2710 ---0 Get 614688    16       string.c  344

23:30:05  2710 0 SMTP accept processes now running
23:30:05  2710 Listening...

Is it a known problem? Did anybody happen to observe similar behaviour?
