800xA SV 4.1 Alarms are appearing after delay time
we are facing a problem 800xA SV 4.1 system with 1oo2 connectivity servers and 2oo3 aspect servers. In the network we have 6 AC450 controllers, we are having a problem from 2 controllers unable to ackknowledge the alarms and the alarms appeearing in the alarm list delayed time. I checked time sync between controller, RTA (PU515), and connectivity server time sync is Ok. Important is parallelly we have Masterview OS connected there also we could not acknowledge the alarms. When I check the alarm details I found uncertain time tag = true for some alarms. But in the same MB300 network we have other controllers where we are not facing this problem.
Could you please help me
Thanks a lot..
