Hi,

I had this before, reading an Excel file generates an out of memory exception.
Yesterday again and I had to restart the server to get VC up and running again.

6/27/2013 9:03:54 AM	Err	Error saving jobfile: System.InvalidOperationException: There was an error generating the XML document. ---> System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown.

I'm reading three columns of a specific sheet. This took 157 seconds.
Today the task went fine and took 220 seconds to complete.

It takes a lot of time, I think this has to do with lookups in the excel file. Isn't there a better way handling this? a Sheet without lookups takes a few seconds...

Erik

Sounds like there is a memory leak in the Excel component or in our implementation of it. When you run this - how is memory affected?

Hi Henrik,

Today I looked at the memory usage of the VisualCronService.exe:

29 Mb - idle
614 Mb - running Excel task
45 Mb - idle
running Excel task
302 Mb - idle
.. after some minutes ..
32 Mb - idle

Last friday I had again an out of memory:

This error came out of the blue. There were no excel tasks running at that time.

This error happens when trying to run a notification after a File write Task. Not sure if related or a general memory problem but perhaps you can try to re-run the Job which this Task is in.

The Tray client logs are ok because whenever a crash like that happens the service is restarted which results in these errors when trying to reconnect in the Tray Client.
