Do you have problems with the actual application when the issue is not
happening? If not, then please don't configure http-no-delay, it will only hurt
the
proxy performance. Do avoid this, its evil.

I assume connection are hanging because of your huge timeouts and
you simply hit maxconn.
> timeout client 300s & 5 minute timeout for clients
> timeout server 300s & 5 minute timeout for servers
I suggest to lower both those settings to something like 5 seconds.

and this to something like 1 - 5 seconds.
> timeout http-keep-alive 1s & 1 second max for the client to post next request
I suggest to increase this to at least 5 seconds or more. Since you make heavy
use of SSL, I would set this to 10 - 30 seconds actually, but YMMV as it depends
on how your clients are using the application.
Also, you should probably tell us the release and the output of "haproxy -vv".
