Greetings,
I am running WL8 Build 32. Since updating I have noticed an increase in the number of Wealth-Lab crashes. Most of the time the crash occurs when saving a strategy to Wealth-Lab.com, but there have also been a few evenings when I left Wealth-Lab running over nite to get the data updates, and when I come back in the morning Wealth-Lab is gone. Is anyone else having this problem? Or is it something environmental on my end?
Thank you

Only Daily providers. If you were updating highly granular intraday data, there's a potential for a memory issue .

This is a tough guess from our vantage point without more information. Maybe you can find some crash information in the Windows Event Viewer to help isolate it.

Thank you for the tip. Found the following two. This was when I saved the strategy to disk and Wealth-Lab.com.

Some research on this 409 indicates it might be related to some system or NET framework corruption:

Does this happen consistent?

No. It is sporadic. Today I have been editing and saving several strategies with no application crashes. Yesterday it crashed three times (prompting my original post). The overnight crashes have occurred ~4 times over the last 3-4 weeks.

After experimenting with a few different instance types on Amazon EC2, I think I have narrowed the cause on this issue to a "Low Virtual Memory" condition in Windows. I have since doubled the amount of physical memory in my local machine to 32Gb and am only using "Large" instance types and above for virtual machines. No crashes in the last month or so. I failed to mention in the earlier posts that I was using a dataset with ~4k symbols, and a daily time series of 25 years. Now, as to how an OS in this day and age can run low on virtual memory with adequate disc space is beyond me. Cheers,
