I can create tickets. What behavior do you see?

After entering all the fields to create the ticket, and then clicking
submit, it would just hang
without creating the ticket.

Forever? No timeout? Just the HTTP POST never returns?

FWIW, I've been experiencing similar problems. In my case, the POST
doesn't return for as long as I care to wait (in one case, around 20
minutes). Re-submitting, sometimes 3-5 times, generally results in a
successful eventually. This is with Chrome Version 54.0.2840.90 (64-bit)
on Ubuntu 16.10.

I'm using Safari 10.0.3 (12602.4.8) on Sierra.

Interesting to check: I'm using HTTP/2 to talk to twistedmatrix.com <http://twistedmatrix.com/>. Are either of you? I wonder if this is a bug in the HTTP/2 stack or perhaps one of the HTTP/1.1 changes made to accommodate the HTTP/2 implementation.

My browser is not using HTTP/2 to talk to twistedmatrix.com (idnar suggests
this is because lack of ALPN in twistedmatrix.com's OpenSSL and lack of NPN
in Chrome).

It might be interesting to upgrade to Twisted trunk to see if some of the HTTP server bugfixes that have landed will address this; however, I can't come up with a coherent theory as to why certain POSTs would just hang.

I've yet to detect any pattern to the problem. With no way to reliably
reproduce the problem and not other real metric for whether things are
getting better or worse, I don't think I could evaluate the results of any
changes.

How often do you experience it? Is it often enough that we could, say, check back in in a week?

My dataset is pretty small... Perhaps 6 or 7 times in the last 2 or 3
weeks? I don't know how many POSTs I've done in that time. Maybe a couple
dozen? I could probably tell the difference if it were *completely* fixed
(or *completely* broken :) so it may be worth making the change on that
basis.
