<iNoah> you know, most free operating systems come preinstalled with their own high horse.

Wonder why these happen though.. How many logins/sec do you get? Have you set login_process_per_connection = no?

Not that many - and I have now. Unfortunately it doesn't seem to make a difference - with the patch in auth-client-connection applied, or direct from cvs:

It's not generating a core file right now either.

I think this is a crash with vpopmail enabled.
#0 auth_cache_clear (cache=0x0) at auth-cache.c:108 108 auth_cache_node_destroy(cache, cache->tail); (gdb) bt #0 auth_cache_clear (cache=0x0) at auth-cache.c:108 #1 0x0804fac2 in auth_cache_free (cache=0x0) at auth-cache.c:100 #2 0x08056de3 in passdb_cache_deinit () at passdb-cache.c:142 #3 0x08056a14 in passdb_deinit () at passdb.c:191 #4 0x080525fb in main (argc=1, argv=0x0) at main.c:273
I don't have any auth-cache directives enabled in my config.

<Dondi5> I must keep track of all this cheese
- Timo Sirainen <tss@iki.fi> shaped the electrons to say...
This crash has been fixed in CVS, but it happens only when the dovecot-auth is deinitializing itself.
Ok - I assume there will be a -test52 soon?
I'm don't really know about the vpopmail problems though.. What backend does vpopmail use for the passwords?
I'm just using cdb.
