Hi, I'm experiencing Exim 2.12 crashes on Solaris 2.5.1.
The crashes appear to be related to `lookup_open_max' and the "close
least recently used lookup file" mechanism. Is this a known problem
with 2.12, already fixed in some more recent version (I couldn't find
anything by glancing at the ChangeLog)?
[ I know, 2.12 is getting old, but as I'm pretty swamped with other
stuff right now, I'd rather prefer it if I could put off creating
the infrastructure we'd need to upgrade to 3.x for just a little
while more... ]
To illustrate the problem, here's the output of a -bh session with
lookup_open_max set to (the ridiculously low value of) 2:
pat$ exim -C exim.conf.debug -bP lookup_open_max
lookup_open_max = 2
pat$ exim -d9 -C exim.conf.debug -bh 127.0.0.1

Segmentation Fault

As I haven't gotten around to compiling an Exim binary with "-g" yet,
the coredumps I get look like this:
(gdb) where
#0 0xef5cc5a0 in _free_unlocked ()
#1 0xef5cc560 in free ()
#2 0x6f578 in cdb_close ()
#3 0x4c67c in search_open ()
#4 0x61f08 in aliasfile_director_entry ()
#5 0x2c018 in direct_address ()
#6 0x58ebc in verify_address ()
#7 0x51430 in smtp_setup_msg ()
#8 0x31774 in main ()
All my lookups but the one for ".../spam_senders" are of the cdb
persuasion... is Exim somehow getting confused and tries to call
cdb_close() on a file opened for a lsearch lookup?
The Exim config we're experiencing these problems with has been made
available at <URL:
http://www.uio.no/~hmeland/tmp/pat.uio.no-exim.conf>.
Any help in solving this would be greatly appreciated,
