I'm no sendmail guru, but .... there rather recently have been a
couple of similar threads, where the askers have a lot of sendmail
children just sitting tehre waiting for a timeout to happen.... and by
default, that timout has been so long that they actually have gotten
hurt by it. "Solution" seems to be to lower the sendmail timeouts.
