Timeouts with 3.1.0 on particular mail items

[A J Thew <aj...@gmail.com>]

We use SA with exim/exiscan (now the same thing from version 4.50).

After upgrading to SA 3.1.0 we've seen a very few mails timeout every time
they are offered to spamd. Initially
this appeared to be an issue with the number of forked spamds but having
adjusted this, we are still seeing
certain mails timeout consistently (they are deferred after the end of
DATA).

We have perl 5.6.1 and had no problems with previous versions.

Is anyone else seeing this?

Thanks
