IDB service occasionally consumes large amount of memory and CPU and becomes unresponsive

Adrian Corston 7 years ago updated by anonymous 7 years ago 4

The customer's Unify.Service.Connect.exe occasionally (every few months or so) enters a state where it is consuming a large amount of CPU and memory and unresponsive.

In the most recent case, it was 3.2GB in size and using 100% of all 4 vCPUs on a machine with 12GB of RAM available.

IDB version is 4.1.5 RTM

HI Adam,

This issue went away when the customer upgraded their SQL server to use better performance disk, so you can resolve it.

I'm afraid there's no way to investigate any further, so I can't answer the connector question.

RedGate Memory Profiler installed and tested.

Since the IDB restart I've run a Full Import succesfully, and note that it took the process from negligible memory usage up to 2.5GB, and since the Full Import has completed that memory usage dropped back to 1.7GB.

Under review

Which connector is running when it spikes RAM and CPU usage?
