Force Rs commented on DERBY-5347:
---------------------------------
I am not a Derby expert, but I do have significant programming experience.
I would not kill the server immediately. At least 2 consecutive failures.
I recently fixed our DB server. We had a watchdog thread that was pinging the
DB and, when the ping failed, was killing the server. I had to change this to
fail 3 consecutive times before killing the server. Having one ping fail was
merely a hiccup (or separate Derby bug).
Just my two cents.
