Spark will sometimes freeze when attempting to start a conversation with a specific user. Our current workaround is to end the Spark process, and rename the transcript folder for that user, then reopen Spark. Fixes the problem every time.
The question is... why?
Someone on my team has the Spark source code and is going to attempt to look for the cause, but none of us are Java developers (I'm just a SysAdmin myself), so we're shooting in the dark.
I attempted a workaround by writing a script that disables the local chat history (since transcripts are stored in our SQL DB), but users hate not having the history and will re-enable it themselves.
From the other posts I've seen, obviously this is an issue for more than us. Does anyone have a clue as to the root cause? Has anyone made an attempt to fix this bug?
