I only get memory leaks if PerlFreshRestart is enabled and I SIGHUP JC it. Perl 5.005_03 has the leaks no matter what. And with DSO, PerlFreshStart is a no-op, since you get a fresh perl no matter what. One of these days I'll take the time to migrate to 5.6.1 and then regression test my whole app, which ain't easy to do on a web-based interactive system where you have hundreds of options to test in combination.

DSO Issues
Hi All, While it seems to be well-known anecdotally that one should never use a DSO install of mod_perl (particularly among Mason developers), is there yet any place where all the known issues surrounding the use of DSO mod_perl are documented? I see a place in the guide where Stas mentions issues with mymalloc and such, but I also saw a post from a few months ago where he'd asked for someone with extensive experience with DSO installs to come forward and discuss the known issues. Did this ever come about? Thanks! David -- David Wheeler AIM: dwTheory [EMAIL PROTECTED] ICQ: 15726394 Yahoo!: dew7e Jabber: [EMAIL PROTECTED]
RE: DSO Issues
Ditto. DSO makes my life so much better in terms of portability and administratability that having my services down for a few seconds during a log rotation is certainly worth it.

If we're collecting a list of things that don't work in a DSO build, add perl subs (via !--#perl sub=My::handler--). At least, they didn't work as of January of this year.
