You will need to restart it or restart qmail altogether and make sure there are no stray proceses that may interfere. I've had multiple instances where the queue becomes abnormally large because qmail-send is defunct.. It should reload and you will see preprocessed mails grow until it spits everything out. -- Jake Roersma Network Engineer Triton Technologies Inc. (800)-837-4253/364-8761
Large queue and iowait
Title: Large queue and iowait I'm having some problems with my qmail server. It seems to be taking an abnormally large amount of time to do queue processing. A recent mailing list send of 250k e-mail's to the server had it stuck in queue processing with iowait at 80-100% the entire time, for over 36 hours. I assume this is not a "normal" timeframe for processing that amount of e-mail. The setup is as follows: Sun Netra t1 - 450mhz ultrasparcII processor 1024MB of memory, 1.5GB of swap 18GB SCSI disk. Solaris 8 qmail 1.03 with DNS and big-concurrency patch If any other information is pertinent, please let me know and I'll provide it. Any insight into what the problem could be would be greatly appreciated. Thanks, Mark -- s/root/Mark
