Has anyone out there running NMS 5.61 and using the data_engine 7.86 seen issues where QoS data is corrupt causing the data engine to queue up? We have a custom probe writing QoS data that occasionaly causes the data engine to stop writing to the database. If we purge the queue, things continue on fine. It's my understanding that sometime after data engine v 7.4ish, it should be able to handle/drop bad messages and continue on normally. Doesn't seem so in our case. Anyone else experiencing something similar?
