Crashing without any warning / logs / traces

[NinjaTrader_Matthew]

calgera1,

I looked into your crash report a little further as I would consider this a critical issue.

There were errors coming from the database in regard to restoring some data from the database, however I do not believe these to be the cause of the crash (perhaps a symptom of the crashing)

Closer analysis of your trace files shows in situations where the application terminated unexpectedly, there was some relevant information contained in the trace file:

2016-10-18 06:55:26:703 *************** unhandled exception trapped ***************
2016-10-18 06:55:26:703 The requested operation cannot be performed on a file with a user-mapped section open.

This error message in particular occurs when we try to write to a file which is in use by another process. Commonly, programs such as Anti-Virus or Backup programs may be locking a file at the time we try to use it, which then results in the crash.

You will want to exclude the NinjaTrader 8 documents folder from any other utilities that may be scanning folders. Here is another thread on that error which contains some information that may be helpful:

If you still experience crashes, please contract our support team so we can look into this deeper. Resetting the database likely would not fix the core issue, and we would want to determine what it is that is locking files that prevent us from saving information as you use NinjaTrader throughout the day.

I'll give it a try and see how it goes. I do not use the computer for anything else but the platforms (nt7 &8) so I can probably just uninstall it completely. Thanks for the help.

I just added the exception and it continues to crash. It seems to be happening around the same time of day around the start of the futures open after 5 ct.

• What anti-virus are you using?
• Specifically what folders did you exclude?
• Can you send us your new log and trace files so we can analyze the crashes before and after the exceptions were added?

I appreciate you working through this item with us. Your experience here will definitely useful for us providing a stable platform for the production release of NinjaTrader 8

Is this on Windows 10? If so, can you double check to make sure Windows Defender is also exceptioned?

[calgera1]

Not sure how to do that

Just noticed windows defender is turned off. sorry i didn't see that.

There were articles about Windows Defender running even if you have other antivirus installed, with the latest Win 10 anniversary update. I run windows defender and nothing else, so I can't yet vouch to that.

Problem STILL not solved after three days! Ninja 8 crashes after the futures open and is unusable for hours after. DO NOT USE THIS FOLKS!

[calgera1]

I guess they gave up on me.
