All,

A bug has been identified in R3.13.6 by Ralph Lange and others at BESSY.

Symptom:

IOCs with a heavy Channel Access put callback load produce "ca put
callback timeout" messages, and may also crash.

Fix:

A patch has been committed to CVS. I have attached the context diffs for
those that need to apply an immediate patch.

Sorry about any inconvenience that this has caused.
