Exception of type 'System.OutOfMemoryException' was thrown

VivekRajendran1 — Mon, 29 Jun 2020 12:18:00 GMT

We are running a process in multiple bots and it is scheduled to run on 24/7. And we have seen the sessions are getting terminated with the "Exception of type 'System.OutOfMemoryException' was thrown." after running for 1:30 to 2:00 hours continuously. Also the runtime resource on resource pc get crashed and the resource pc loses its connectivity from Interactive client. What would be the cause of this issue, please advice.

I would like to answer this as per my knowledge.
Having 200000 records in it will certainly make it out of memory. To load them, what I used to do was opening my Task manager and free up some memory to give a temporary run.
It will no throw this exception at that moment, not a permanent fix.
Plus, I believe loading 200000 records would make no optimization. Better make a query to filter out the result and then load it.
Please correct me of wrong.
Thanks.

I have the same issue with this error.

We recently increased the memory on the resource pc from 2 to 4 GB, and we see that it crashed the resource at 2,7GB.
We're trying to load in an invoice with roughly 50 000 rows from a 4,4mb xlsx document.

Trying to check the KB article is proving impossible for me, as all I get is a list of your offices.
When trying to navigate to the support center manualy after logging in, it just shows me a list of your offices again. I've tried it in different browsers, and on different pc's located on different networks.

Hi Leon - in the past I have issues with the BP site (especially the Digital Exchange) due to cookies. Can you try to use incognito browser and access the link there after login? If it works there then it is a cookies issue with the browser.

Best of luck,
Seraj

We solved this by downloading the invoice as a csv instead of an xlsx file.
Far less memory required.

The issue with not being able to get to Support Center was an account issue. It wasn't connected to my company correctly. It has now been fixed after talking to support.
