SpamAssassin timeout OT: SpamAssassin timeouts

The lookups from osirusoft were causing a problem and spamassassin was
timing out while doing these checks.  What I noticed was that MailScanner
was continuing to use spamassassin at 75 consecutive timeouts out of a
possible 20.
When the number of timeouts hit 20, it should have stopped using
spamassassin (I don't think I'm makin this part up, it's in the
documentation and has been mentioned several times on the list) until the
next restart.  At next restart the counters should drop to 0 (assumption on
my part) and if it hits 20 again, it will stop using spamassassin again.
Instead, spamassassin was continuing to be used even with 75+ consecutive
timeouts and kept queueing up the incoming mail because of this.

Since MS has nothing to do with mail delivery, I don't think you can point
the finger at it.  Yesterday, about 2PM CST, I started getting complaints
from people not being able to send email...connections were timing out while
sendmail attempted to look up via osirusoft.  I removed that from my, and everything started to flow again.

I think there is more to it.  I've always use skip_rbl for SA because I use
the rbls on the MTA side and I've been seeing the mail backing up in queue.
This also started happening after I updated to 4.11-1 on Sunday. I think
it's Mailscanner and it's mother process not restarting properly.  What I've
noticed so far is that I only have 3 MS processes running even though my
setting is set to 5.  Once process has been running for 4 hours 11 mins and
the others are the spawned processess. If I kill MS and restart then I get
all my processes back.  If I look at my logs, it looks like only one MS
processes was doing anything.

Unfortunately something that I noticed yesterday when the RBL's were offline
was that MailScanner was not ceasing to use spamassassin even though I was
up to 75 consecutive failures out of 20. I just upgraded to the newest
MS-4.11-1 yesterday as well. RedHat 8.0 if it helps.

I think you're misunderstanding the comment slightly.
If MailScanner doing RBL checks notices that they've timed out a number of
times in a row it will stop using the RBL checks till the next MailScanner

If you do the RBL checks within SpamAssassin this means that SpamAssasin as
a whole will time out and cannot "disable the RBL checks" itself (as
MailScanner does). In turn MailScanner should see that SpamAssassin is
timing out and disable it till the next MailScanner restart.
