Sudheer Vinukonda commented on TS-2983:
---------------------------------------
Turns out that enabling probe for http also may be corrupting the requests.
Apologies for the misinformation, I may not have run it long enough earlier.
The https corruption was happening so often that, it was clear within a minute,
but, the http issue seems to be happening with really low frequency (once/hour
or so) - this may also be due to the generally lower percentage of http
traffic on our host. Anyway, for now, turning off both http and https probe and
we are back to trying to find the root cause.

> After a lot of debugging, figured that the request was getting corrupted even
> before remap and in fact, is being parsed incorrectly at the read request
> state. Further analysis lead me to the commit TS-2197 (commit
> 30fcc2b2e698831d1a9e4db1474d8cfc202818a3 in Oct'13), which has altered the
> way the request is read slightly. Reverting the commit seems to have fixed
> the issue.
