I have learned that with a chrooted environment nothing is a drop in ANYTHING. I plan to have a good long overlap on the two servers, so I can play with the new one and get it right without upsetting any of the paying customers! Unless Postfix could be installed alone side of Sendmail and used just for MM. I've not looked into that, but I have a bad feeling about it. I've googled for the problem and at least two other folks changed MTA's and the problem went away... No other solutions though. Well that is my long term fix. Thanks.

Re: [Mailman-Users] Re: qrunner with over 90% CPU
Sorry to pepper you with so many questions... but here are some more... What do you get when you type: cat /proc/sys/fs/file-max cat /proc/sys/kernel/threads-max On one of my well-running RH 9 boxes, I get: cat /proc/sys/fs/file-max 26208 cat /proc/sys/kernel/threads-max 4095 You can adjust these values by becoming root and typing in something like: echo 16384 /proc/sys/fs/file-max echo 2048 /proc/sys/kernel/threads-max Note: this is not a recommendation (well it is, but it's not *my* recommendation...) BTW: I'm guessing that you are not running either NFS or NIS (NIS is a way of sharing user information amoung a lot of unix servers) I also guess that hda1 is your /boot and that hda3 is / That indicates that your install is using one IDE drive. I hope your mail traffic is not too high! You might want to drop the Open Relay checks for a week and see if that makes a difference. I'm not sure, but Sendmail may be holding open the access.db file while it does these checks.

Could be, but my lists are currently announcement lists that send at a low mail time. I once let the runaway process go for 15 minutes to see if it would clear, it did not. The open relay checks cut my mail volume substantially, and I suspect I'd hear from some customers if I stop them. Well my thought, isn't that the checks are continuing on forever. I'm thinking that something in the Sendmail install is very time sensitive and that the Open Relay lookups stretch you beyond that time - holding open the access.db file (without proper locking). So that when some other child process from Sendmail attempts to access the access.db, it is blocked and never cleared by the parent. I've googled for the problem and at least two other folks changed MTA's and the problem went away... No other solutions though.
