XF 1.1 RSS Feeds on forumlist not working

[melbo]

So I just recently converted from vB 3.8.7 and am working through some small issues as a result. A member mentioned that my RSS feed buttons next to each forum return empty results:

Any ideas on where to start tracking this down?

Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data.

What is the name of that process? If it's PHP then you need to look at your PHP extensions.

I've encountered the exact same issue. RSS links do not work and generate a message in the apache logs:
child pid <x> exit signal Segmentation fault (11)

I'm also running APC. @melbo, were you able to find the cause of this issue?
