9027	[CRASH] BE segfault on start of recording 3 HD programs (HDHR)	Dave Alverson <dalverson28@…>	danielk	"My FE/BE was set to record three HD programs starting at 8pm. 2 were on the same multiplex. The BE segfaulted as it was starting. Encoders 1-4 are HDHR, 5-6 are AirStar HD5000. The input is TWCable. I noticed at 8:35 the 2 tuner lights on the HDHR were off and determined it crashed and restarted the BE and it started recording 3 programs fine. Heres a summary; details in attachments.

Looks like cs->sock is -1, I think thats the problem.
