All unexpected restarts. Inexplicably both frame writers have become unstable, starting about 24 hours after Tuesday's solaris reboots. I may try another solaris reboot today.

I've attached a trend of the h1fw0 and h1fw1 restarts for this month (h1dc0 restart is included to show intentional DAQ restarts). The instability starts 1/13 when we upgraded to RCG2.9.

Conlog frequently changing channels list attached.
