We have been running
the new gateway 2.0 on epics 3.14.8.2 for a month or more with good
results. It has been stable even with large transfers.
However last evening
a problem occurred with the gateway and it had to be restarted. Unfortunately
the only information I have is the following gateway log.
Can anyone hazard a
guess as to what was going on ?
We are running the
gateway on Redhat Enterprise Linux 4.
Also we are
running the alarm handler through the gateway too which I understand from
previous Techtalk emails is a bad thing (DBE_VALUE v DBE_ALARM events
subscription conflict) and something we have to
address. Could this have caused the problem?
