[Freeswitch-users] problem using mod_managed under linux

[Michael Giagnocavo]

Hey there,

	If anyone has problems with mod_managed, please email me directly. I'm finally maintaining it again.

	I just uploaded a patch:
http://jira.freeswitch.org/secure/attachment/14903/mono_update.patch

	This integrates the 2.8 mono patch as well as fixes a configuration issue when starting mono. This should solve the issue of having to use the mod directory for the current directory, or having it not find libc, etc. 

	I've tried it on Ubuntu 11 and SL 6.1 with Mono 2.10. I'm installing Ubuntu 10 LTS to try it out there.

Thanks,
Michael

OK, it was actually in mono that the error occurred, but last couple of times, it did work, but I didn't change very much.  I hope it get fixed soon.  The end of the stack was libc.so which has always been suspect for me.

Thanks again for your response.

Your life is like a penny.  You're going to lose it.  The question is:
How do
you spend it?
