SpamAssassin being killed

[Bill Anderson]

I just started getting a bunch of these in my log file and MailScanner will
stop scanning for mail for spam:

Oct 31 00:33:04 xr400 mailscanner[12044]: SpamAssassin timed out and was
killed, consecutive failure 10 of 10.

I know I can up the number, but why is this happening?  Is there anything
else that can be done as well.  Thanks.

I am running version 3.23-4 of mailscanner.
