IPCAM App stops responding after external login

[GSVNoFixedAbode]

I've got ipcam installed on an up-to-date iPhone 4S, with port mapping and security.  If I 'log in to the camera from an external address it works, but after I disconnect, the app appears to freeze/crash and doesn't respond. When I physically get to the phone the app is no longer running. 

No SIM card, Do Not Disturb set, and all notifications turned off.

Suggestions?

If iCam is crashing, there should be crash logs.

Here is the direct link for instructions on how to locate crash logs from your iPhone/iPad: http://www.ondemandworld.com/how-to-find-crash-logs/

If you find any iCam crash logs, please send the most recent ones to support@skjm.com and we will hopefully be able to further troubleshoot the issue. Also, please reference this post and your username in the email.

 I now suspect the timing of connecting from external was coincidental and gave a false indication of the issue.  It definitely seems to be time/use related.  I have a script that grabs a copy of the image (via cURL) every 15 minutes, and in just on 20 hours the app appears to stop. 

How long do most people have the app running on an unattended phone - 1,2,10+ days?

  Ok, may have found the primary culprit for this and it's not the ipCAM app itself. 

Putting an iPhone up against a window as a webcam on a sunny winter day means the phone is in full sunlight for a few hours: enough time for the phone to get to a high temperature and stop working.  The high temp screen comes on and stays there until the unit cools enough to continue.  However, like any other interruption, the running app is now in the background or stopped.  I found this out when home on the weekend and able to get to the iPhone after it had stopped responding.

I've since put some reflective insulation between cam and window and the device is a lot more stable.  I currently scrape the app webpage every 15 minutes for the image, logging any failures.  Over the past few days I've noticed a few times when the  app doesn't respond but then comes right later. For example 10:00 success, 10:15 fail, 10:30 success, 10:45 success ...  That's acceptable for my purposes.

So the moral of this story is to remember placement and device operational environment as well as the software itself!

Thank you for the update!

We were having a heck of a time trying to replicate this issue, letting ipCam run for days getting hit by your curl script without seeing any issue, so I am glad you found the cause of the issue! 

On note, if you are seeing sporadic failures when accessing the image that are later resolved it may be due to the device losing its WiFi connection for a brief time, and then regaining it.
