[Exim] Exim 3.22 problem on Solaris 8

Exim users,

I've run into a problem with Exim 3.22 after upgrading to Solaris 8. I'm
not exactly sure what is going on, but it appears that many copies of the
same bounced message (different message IDs however) generated by Exim are
getting frozen and stored under /var/spool/exim/input. These frozen
messages are stored as body only, no header, and they are filling up the
/var filesystem very fast:

-rw-------   1 exim     mail      155648 Dec 18 16:35 16GNCp-0007IZ-00-D
-rw-------   1 exim     mail      155648 Dec 18 16:35 16GNCr-0007JG-00-D
-rw-------   1 exim     mail      155648 Dec 18 16:35 16GNCt-0007JR-00-D
-rw-------   1 exim     mail      155648 Dec 18 16:35 16GNCu-0007JT-00-D
-rw-------   1 exim     mail      155648 Dec 18 16:35 16GNCy-0007JX-00-D
-rw-------   1 exim     mail      155648 Dec 18 16:35 16GND0-0007Jd-00-D
-rw-------   1 exim     mail      155648 Dec 18 16:35 16GND2-0007Je-00-D
etc., etc.

When issuing:

bash-2.03# exim -Mvb 16GSyC-0006Vt-00 | more

The rest of the body is the same garbage as line above.

It seems like the perl rules file (exim.pl) is failing somewhere. Does
anyone have any ideas? Thanks.
