Re: word socket in log file

[Liam Slusser]

All -

Just wanted to follow up.  These "socket" in the log file seem to be caused by a connection to the socket listener but never handled by python hander.  So a TCP connection and request happens from the clients prospective and gevent seems to be aware of the request (it logs it) but the handler call to __call__ never seems to happen - so the request just times out.  I haven't done any other investigation.

I've downgraded gevent from 1.0rc2 to 0.13.8 and the problem has disappeared.  I've also noticed that our monitoring has since had zero issues talking to our service.

We do around 40 million requests a day with gevent and since the downgrade all is good.

thanks!

Hey All -

I'm having some logging issues with gevent 1.0rc2 using the pywsgi module.  Seems that a very small number of connections I see the word "socket" instead of a http code in the log file.

And when this happens it seems like the connection just hangs, as seen from the TTLB.  Here is a few tests using wget on the same server.

In our production logs I also see "socket" now and then as well.  As of today, out of 4 million requests, it has happened 365 times so its a fairly small number.

Thoughts?

thanks!
