timeout-failure in mailscanner

[Piper Andreas]

Hello all,

there seems to be a small, but malicious bug in mailscanners sweep.pl (all 
versions, I assume), which corrupts the killing of a timed-out virus-scan-
process and gets mailscanner stuck, if the process can't be killed with the 
first 'kill -15' (which happened here with a .exe-attachment and 
mcafee-VirusScan)

I did some digging and ended up with the following patch (for version 3.03,
should be quite similar for earlier versions), which solved the problem for 
my site:

*** sweep.pl.orig       Wed Jan 23 14:50:20 2002
--- sweep.pl    Wed Jan 23 14:50:34 2002
***************
*** 348,350 ****
        sleep 1;
!       ($pid=0),last if kill(0, $pid);
        kill -15, $pid;
--- 348,350 ----
        sleep 1;
!       ($pid=0),last unless kill(0, $pid);
        kill -15, $pid;
