Bug Description
Dirk mentioned at the codeathon that in some limited number of rare instances (maybe twice) an IOC never reconnected the client side when the IOC that it had a db ca link to dropped channel access because of too high CPU load at the server end. Removing the server end CPU load and rebooting alone did not help. Writing to the link name field on the client side in the database _did_ cause the link to reconnect.
We may need to get a stack trace for the timer queue thread running at similar priority to the db ca link ca client context in order to get this fixed.
