Bug Description
IOC resident CA server put callback failure
Symptom: IOCs produce unexpected "ca put callback timeout" messages, and may also crash.
Additional information:
Scope: The bug is present only in the IOC resident CA server. It was introduced in R3.13.6, and will be more likely to occur when there is a particularly heavy Channel Access put callback load.
This bug was detected at BESSY by Ralph Lange and others.
