After upgrading to a recent STABLE, I have been seeing the
following sporadic errors
Aug 28 04:15:15 smarthost2 kernel: TCP: [xx.yy.165.120]:53617 to
[xx.yy.164.50]:25; syncache_socket:
Socket create failed due to limits or memory shortage
this is with
FreeBSD 8.1-STABLE #7: Wed Aug 25 15:32:05 EDT 2010
and the previous kernel was from July 20th.
When sendmail is deferring the connections it should not show up
in the syncache logs. The accept() by sendmail is much later than
when the socket for a new connection is created in syncache. Here
it points to the limits in the listen queue. Maybe sendmail is
getting behind in accepting new connections and the listen queue
is overflowing.
How would I track that down to confirm it ?
