Title: prefork: server reached --max-children setting, consider..
Post by: mdo on March 28, 2007, 11:06:42 AM

The full message (in spamd/current on SME 7.1.3) is actually:

 prefork: server reached --max-children setting, consider raising it

This seems to happen only at "busy" periods (several emails arriving at the same time). A typical sequence:

at the "not so busy" times it looks like this:

Any suggestions whether to change/"raise" (?) which setting?
Thanks,

Please raise anything which doesn't "just work" via the Bug Tracker. Thanks.
