I'll try that next. I've been standardized on perl
5.6.1 for a while now and had no reason to upgrade
(till now perhaps). Does 5.8.2 mix well with
apache_1.3.29 and mod_perl?

I've already replaced my complete perl install (in a
different location), including all perl modules. [And
yes, I used the cpan shell's 'autobundle' feature.]
Same exact crash still occurs.

True, I can't reproduce it without perl & SWISH::API.
Haven't tried without zlib yet.
HOWEVER, unlike yesterday, today I was able to
reproduce the exact same problem on a completely
different machine. Both machines are running
swish-2.4.0 and perl-5.6.1; one is RH-6.1, the other
I'll try with perl 5.8.2 (and using 5.6.1 without
zlib, but that will take longer) and report back the
results. If anyone has any good ideas about how to
detect where things first go wrong in the heap with
perl (IE, what causes this problem in the first
place), that would be useful too.
Here's two stack traces from the second machine to
exhibit the issue. It's clearly some kind of double
