Over the weekend, immediately after getting the 1755260 update, spamd went into kind of a tail spin in which it would no longer spawn new children. After about 90 minutes, all other children are killed, leaving spamd running but not actually able to process anything.
Googling indicates it has something to do with the "select returned error on server filehandle" error, but I'm not finding much other than that (like the actual cause or a solution). It seems like it has something to with the sa-update, but whether it's specific to the update in question or just that an update took place isn't obvious. Did anyone else see an issue what that particular update? This is on Ubuntu running 3.4.1 (3.4.1a-0b~trusty to be exact), with spamass-milter calling spamd (with default children settings).
