Procmail / sendmail hogs all memory - system slows to a halt.
System P4 2.4GHz/512M/1 GB swap/ RedHat 9.0 + updates
I ran the command-line version of Seti for the first time last week.
Since then [though it may just be a coincidence] I have noticed that even after disabling and now deleting Seti:
a) Sendmail and Procmail are high up in the 'top' listing, with Procmail taking 450M of memory or more ! Needless to say the system grinds to a halt eventually - windows and icons are slowly painted row-by-row until you can't even log out or switch to another console Ctrl-Alt-F2 to shut down.
b) The directory /var/spool/clientmqueue gradually fills up with files called dxxxxxxxxxxx where x...x is an alphabetic string, each up to 2 GB in size.
c) checking the 'mail' mailbox I find some large messages apparently sent by cron. No user has a cron entry.
If I disable Sendmail from starting as a service at boot time, I don't get this problem - however I can't consider this as a proper fix !
As soon as I restart Sendmail, the decline begins, and I have to reset or power off if it's left too long.
Something has become trashed somewhere, and I'm blaming Seti at the moment !
