[mythtv-users] Segmentation Fault due to dirty wlan connection?

[Woody Sturges]

It appears that my backend server seg-faults when my frontend box has 
trouble with the wireless lan I have setup.  My hardware:

Backend:
500MHz PIII
384MB RAM
3 IDE drives, each a separate mount point, all ext3
RH9, Myth 0.13 (Axels/Jarod's config)
PVR-250, and a M179
100Mbit Ethernet (direct connected to the LAN)

Frontend (downstairs):
AMD 2600+
512MB RAM
Small IDE
RH9, Myth 0.13 (Axels/Jarod's config)
Netgear PCI 11.g wireless card (talks to an 11.g AP upstairs in my office)

I can usually get it to happen when I stand in a particular location and 
cause interference on the WLAN.  It looks like packets are dropping or 
getting mangled.  This results in the *backend* server throwing a 
segmentation fault.  Below is a brief backtrace from gdb:

I'm assuming it's WLAN related, and I know I need to fix the WLAN signal 
quality.  The frontend is sitting next to my reef tank, which probably 
generates a LOT of electrical interference.  I can't easily pull a cat5 
downstairs.  I'll probably try moving my AP somehow.

Anyway, is there something I can do to make the backend more forgiving of 
intermittent crappy connections?

Thanks in advance for any help,
Woody
