This morning I was on the UI3 in my office computer and wanted to download/save a clip that was recorded overnight. I did the usual "start" and "end" and clicked the export clip. Not a huge event recorded time. I suddenly got several server errors, attempting to reload..etc. and continual cascading errors. Then the BI system basically "locked up".
I went out to the main BI computer and it was also "locked up", with red error bar, and all the clips on the side panel were not showing. I went to the LOG and tried to see what happened. I then tried to "rebuld database" as none of the past clips were showing. The BI system kept shutting down. Reboot. Came back but still big red bar at bottom and none of the clips showed.
System stopped recording from camera as well. Frustrated I went back to my office computer and had to get into the Log for the UI3..and then finally I found the part with the que for downloading clips...and it was frozen. I was able to "Cancel" the download... then the system became unfrozen and back to normal.

I don't know why this time, doing a standard download of a clip could lock up the entire system. I am using a Unifi router with a 2.5Gb connection via ethernet.

For about 20 minutes of trying I thought there was a total failure...but the only thing that brought it back up was getting in the remote desktop via UI3 and cancelling the "save clip". Did not know that could basically shut down the system.

I am on 6.1.3.9 and I tried an MP4 export and it worked fine for me, what format are you exporting to? Have you tried the export from the BI console to see if it is related to UI3

Here is my export screen from the BI console

I will try an export from UI3 to confirm that also works for me!
 
Just tried in UI3 and the export is working there also, Is it possible that you need to rebuild the database, you mentioned that you did this, did the rebuild work or did the BI system crash when you tried to do the rebuild?
 
Questions. I only UPDATE the latest STABLE.

I export in MP4 only.

When I export from the "main" PC where BI resides...it never fails.

This is the first time ever (I do an export once a week or so..) from the UI3 that it "locked up".

It has not happened again. I posted this in case someone had a similar event.

The possiblities may include factors outside of BI, such as a tranisory issue with Windows, or the server.

I'll post again if this repeats, but I am thinking somehow the data got corrupted or something and BI went into
some mode of waiting for the files... don't know
