---------------------------------------------------------------
It turns out that TS-2197 is not really the culprit - the errors appeared to
have stopped for a few minutes, when I reverted TS-2197, but, appeared again.
:-(
Investigating further, it looks like, the commit in TS-2751 may be causing this
issue. I suspected this to begin with, but, was hoping seriously, that it was
not. Given that it's a relatively large commit, it may need to be reviewed
carefully to identify the root cause.
For the time being, reverting TS-2751 and running the private version for an
hour in production, did not bring back the errors so far - will continue to
monitor and confirm/update, if there's anything else.
[~jpe...@apache.org] - We are only seeing this in production. [~bcall] and
myself have not been able to reproduce it, but, our ops team was able to
reproduce consistently (but, again only in production), using Safari browser.
Will let you know if we manage to find an easier way to reproduce it.
And yes, this is definitely a blocker for our 5.0.x (and in turn, SPDY)
production roll out - it would be interesting to hear if anyone else, using
5.0.x is also seeing this issue.

> After a lot of debugging, figured that the request was getting corrupted even

> 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.
