Uncaught TypeError: Cannot call method 'concat' of null #145

Occasionally receive Uncaught TypeError: Cannot call method 'concat' of null on Chrome. I think this is caused by session sharing but I can't be sure.

Yes, it's caused by session sharing. The exception means that shared session was found so the socket tried to use but it failed because important properties are not found.

Handling session sharing is similar to multi-thread programming in server side. Not easy to test if it works as expected. Also, there is no such locking support now. Anyway, I will rewrite this part considering your issue.
