Great job! Congratulations on solving the mystery and thank you for your perseverance on tracking down the process hangs! The Compress-Raw-Zlib version 2.017 is from 28 March 2009. Its changelog does mention a core dumping issue when LimitOutput was used, although I don't see any use of LimitOutput in either the Compress::Zlib or Archive::Zip, so I guess the problem had a wider impact than documented. Btw, I believe the FreeBSD users stand a good chance their Compress-Raw-Zlib is more recent than what is included with Perl 5.10, as amavisd-new port makes a dependency on p5-Archive-Zip, which in turn depends on p5-Compress-Zlib and p5-Compress-Raw-Zlib from ports, not from perl core modules.
