I receive this error sporadically while using a site which worked perfectly up until 4.3.1

If I reload the page the page executes properly.

I am facing the same problem of session_start The session id contains illegal characters. This is due to invalid characters in session_id. Session id is generated randomly. Please let me know PHPSESSID is contains invalid characters.
