Issue with resource PC - showing disconnected in control room

[MayankGoyal2]

Hi, When running one particular process from control room, the VM starts showing disconnected in control room after around 1.5 hrs. This is happening everytime and after around 90 minutes. There are other process which runs good even for 3-4 hours. 

Also once it gets disconnected, after that when its up next time BP is not identifying any object on chrome browser with browser mode till we dont restart the machine.

I am not sure how a process coding can cause VM to show disconnected in control room and how these 2 are related. Also not sure if chrome BP addin communication can be a issue because this process is doing all UI actions on Chrome browser.

Hello Mayank

There is a possibility that the runtime resource might be crashing due to which it is going offline. I would suggest you to check the Blue Prism Window Event logs for the specific time duration to see what is causing the Runtime Resource to go offline.

Hi Mayank, 

Looks like a memory issue. Try implimenting garbage collection action in between consicutive UI automation calls to object that will allow system to reclaim memory. Also avoid parameter logging in stages that handles collections. And change logging level of object and process to errors only. 

Even though you have 64 bit installation of BP the underlying process is still 32 bit hense it cannot claim more than 4 GB Chrome also consume memory which could lead to unavailablity of shared memory. Resulting in abnormal termination of resource pc

@JerinJose - Thanks a lot for your response, is there a way in BP or is there some place on Windows OS where I can enable and check the memory usage logs for Chrome and BP resource PC process. I want to see the maximum limit this is reaching and causing resource PC to crash completely.
Also if I explicitly call garbage cleaner via code stage, will that make any difference?
