Possible unmanaged memory leak?

ericberman commented 4 years ago

Or an issue with large video files being uploaded? Are we ever trying to load that into a memory stream?

I think I've caught all of the key IDisposables that were not being disposed...closing out for now.

Happened again yesterday. This time in CSharpDateFormatToMySQLDateFormat (which I can probably kill); I think that's a red herring.

I've also increased disk size and changed the VM settings to let Windows manage VM swap size; that too could have been causing this. And commit 1e98d77fedc8e39471e9c2104afa43600fe7bd65 removed localecode/shortdate, if that made a difference (which called CShapDateFormatToMySQLDateFormat in stack trace above); that code is now orphaned. I'll keep an eye out here, but for now will close.
