Runaway CPU #15
Description
I have had three incidents in as many weeks where the CPU has gone to 100%. The remedy is to first restart urfd. At this point, usually only 1 or two tcd channels (out of 3) are shown as reconnected. They I need to restart the remote tcd and everything works for a time.
Environment for ufrd:
1 vCPU cloud Linode cloud server.
