Hi

I updated to the latest db44 but it didn't fix my issue. Still have
"(!!)TROUBLE in child_init_hook: BDB no dbS: Unknown locker ID: 2198
errors. . at (eval 64) line 30".

"Creating db in /var/amavis/db/; BerkeleyDB 0.31, libdb 4.4". I run
everything in a ram disk but I hadn't such locking issue with 2.4.x.

I run 4 mail servers, all with the same configuration and OS and nearly
same hardware. But it looks that not all machines are affected in the
same way. Some of them have more problems than others with this "unknown
locker" problem.

Now I set $db_enable=0 on the machine where I get this locking issue
every few hours. I hope this fixes it. how large is the speed impact
without db_enabled?


Regards,
Thomas
