Supplement:
At present, we have found that there are such problems in the two application
environment which common websocket and http, both of which use websocket with
no errors，but only http has error 500 . There are no missing parameters in the
corresponding code of 500 requests in the access log.
Difficult:
It is hard to obtain the thread dump of exception thead, due to the
corresponding request error quickly within 200 millisecond.
Investigation progress:
We found some differents after comparing the error report with the normal call
relationship:
