Hello
I have a redundant system (2 servers). Citect 2016. For this situation one server is running as a service and the other is not (to have better debugging)
The alarm servers are taking care of about 30k digital alarms and some advanced.
This has been working for years without problems but recently I add some motors and more 2k digital alarms and one of the alarm Servers crashed (at night of course) with out of memory message in the log. I check the memory used by the alarm servers and they start about 900Mb and grow until about 1.2 Gb (primary and standby is the same)
One of the things I tried to solve the situation was to activate the "Extended Memory" in both alarm servers, but the one running as a service doesn't start with configuration error or something similar.
Someone is using Extended Memory in a alarm server running as a service?
Any other advice for the out of memory problem (other than delete alarms, add a new alarm server, implement clusters)
