Hi,

has anybody ever really tested or used "PerlInterpScope handler"? Normally mp2 on worker MPM works well enough for me, at least stability-wise, but if I enable that potentially useful option, all hell breaks loose when I simulate a few simultaneous requests via "ab -c 2". Lots of segfaults and random nonsense Perl errors, probably triggered by memory corruption.

Since I had that option in my httpd.conf commented out for a long time, this is probably not a new issue, and not specific to any exact Perl or Apache version.

I'm assuming here that the threading issues talked about recently only apply to self-launched Perl threads (which I don't use), not normal mp2 interpreter threads.

Markus, normal mp2 interpreter threads are exactly the same as the threads you spawn from threads.pm (all created by perl_clone() C call). So the same problems apply. As you have suggested "PerlInterpScope handler" is not tested. Therefore there could be various sources of problems. Most likely the issue I'm trying to solve now. Feel free to send new tests that demonstrate the problems and we will look at those :)
