[Mono-list] Server using mod_mono

Sat, 10 Jul 2004 15:35:13 -0400

Patrick,
	Another thing I had done on my gentoo box was to NOT enable NPTL.  Back in 
beta2, I experienced some odd behavior on my gentoo box with NPTL enabled.  I 
removed nptl from my USE flags, recompiled glibc and then reinstalled mono.  
After that, things were fine.  I never got segfaults, however, the site I was 
working on would just hang and never return a page.
	Do you have nptl enabled?  Maybe it would be worth a try to disable?

Good luck,
	-Mike
