All,
A significant bug limited in scope to EPICS release 3.14.5 has been
discovered by Ken Evans. The problem is related to Channel Access monitor
subscriptions not updating after a TCP circuit experiences periods of
temporarily unresponsiveness. Please see entry 78 in Mantis. A patch has
been applied to CVS and a fix will be included in R3.14.6. Sorry about any
trouble that this has caused.
Jeff
A decision was made to add a change to EPICS R3.14.5 so
that when a TCP circuit is temporarily unresponsive then
the channel, but not the circuit, is immediately
disconnected. This change was determined to be necessary
to improve overall system robustness in the face of
IOC or network overload.
Unfortunately, an error was made when installing these
changes which could cause a subscriptions to stop
updating if a circuit is temporarily unresponsive.
