This does look like a widespread serial communications fault. In the
past having a burst of TPM errors has been a symptom of high network
loads as evidenced by the Watcher's tpmHandler encountering an
EPICS channel access timeout. The lack of a channel access fault in the
watcher errors rules that out. I also find no glitch in the archived
data on sdsscommish that would indicate a network problem.
