R3.12 BUG Report
(CA client fails to properly clear event when channel is disconnected)
SYMPTOM:
Assert failure in bucketLib.c when ALH/probe exit and the IOC is
disconnected.
FIX:
Properly clear event resource when IOC is disconnected.
A patch will end up in a 3.12 bug fix release.
EXPLANATION:
This bug occurs when all of the following are true:
o You called ca_clear_event() prior to calling ca_clear_channel() instead
of calling only ca_clear_channel() (and letting it clear the event).
o The channel was disconnected when you cleared the event.
It appears that this leak has existed for a very long time and was not
detected because most applications call ca_clear_channel() to clear
both the event and the channel. This was caught because the new resource
id table code didnt allow itself to be deleted while a resource id was still
in use.
