The messages about "munged shared memory" seem to be going if you change
my($tag, $ice) = unpack 'A14 A*' = $stuff;
in the file lib/IPC/Shareable.pm, sub _thaw to the:
my($tag, $ice) = unpack 'A13 A*' = $stuff;
(since the sub _freeze calls
my $stuff = 'IPC::Shareable' . $ice;
- i.e. 13 chars). But there are further problems ("make test" hangs)...

I had some problems with make test, one of the tests doesn't return and I got a few munged shared memory segment errors, I was attempting to install under Solaris 7 and Perl 5.6.0. If not IPC::Shareable, what module do you use for fast communication between Apache-children? I started with IPC::SharedCache since it did most of what I wanted, but took Sam Tregars advice and went with IPC::ShareLite (and serialised all data myself with Storables freeze thaw methods) and it works a dream. One thing I couldn't seem to do was delete() tied IPC::Shareable hash elements without getting the aforementioned "munged shared memory segment" errors, which I can do with IPC::ShareLite. -- steven

From: "David Jourard" [EMAIL PROTECTED] Has anyone worked with the LWP module under mod_perl and have they found that it works with no modification.

"make test" hangs for me on these platforms and the module author is unreachable :-( http://vorpal.mcs.drexel.edu/bsd-ports/helix/shared-memory.html doesn't seem to help on OpenBSD (increasing SHMMAXPGS up to 4096) If not IPC::Shareable, what module do you use for fast communication between Apache-children? IPC::ShareLite is writen in C (and hence faster (arguably)), but it does not serial data structures, so either Freeze / Thaw or DataDumper are you friends here. I've seen IPC::Sharable working ok on Solaris 2.6 but cannot offer any guideance as to why it may not work. Greg
