Hi all, Running Exim 4.69 on 7.0-RELEASE-p6 FreeBSD. The box has been recently upgraded from 6.3 (like 24 hours ago). Currently Exim is sending the following lines to the log files. 2008-12-01 19:02:35 Failed to get write lock for /var/spool/exim/db/callout.lockfile: Invalid argument 2008-12-01 19:02:35 Failed to get write lock for /var/spool/exim/db/callout.lockfile: Invalid argument 2008-12-01 19:02:35 1L74Cp-000GRN-3R Cannot lock /var/spool/exim/input//1L74Cp-000GRN-3R-D (22): Invalid argument The permissions are all correct for the spool directories and for Exim itself. It is creating stacks and stacks of 0 byte files in the message spool directory. I have recompiled all the ports but to no avail. I've upgraded 2 other machines with 99.0% the same setup with no issues. The only difference is hostnames/ips and that this machine is running mysql on it. Everything else on the machine (spam-assassin, clamav, mysql) is working fine. Has anybody got any ideas, other than downgrade back to fbsd 6.3? Cheers cya Andrew
