Hi Niphlod/Michele: Thanks for the suggestions.
Will put a rate limiter in front of Rocket just to be sure. I wasn't able to see anything in the logs, actually, all I have is the httpserver.log. How can I get web2py to log more what its doing internally? -D 100 didn't do anything, or maybe I didn't know where to look. If web2py could tell me where its stuck that would be most helpful. Concur on the SSL, we've noticed that this happens mostly on the SSL part. Also, I've noticed it happens a lot more if we have multiple interfaces on the same web2py process. Interestingly, on a different installation, this happens too, and hangs more often if I edit a file. If I don't touch them much, they seems happier :( This is leading me to believe that its something I'm doing in the application that is causing this behavior. But the apps themselves are generally fairly simple ones, forms, grids and mysql. As a temporary hack, for now I run multiple web2py processes, and haproxy in front of them, and have monit monitor each of the individual web2py processes and kill/restart them if non-responsive, but this isn't fixing the problem, just bandaging over it. Again, thanks for the input. -wasim On Tue, 25 Oct 2016 at 14:11 Michele Comitini <[email protected]> wrote: > @Wasim are you leaving some web2py shell open with a db transaction going? > > Check uptime of your machine to see if load average is high or your run in > a dead-lock. > I see you are using certificates, I found that python ssl sockets have > some quirks depending on python vs openssl version. > > Of course follow niphlod suggestions and keep in mind that it is easy to > be under DDos attack, again it is better to use a dedicated SSL fronted > server instead of python in the open internet... > > > > 2016-10-24 12:44 GMT+02:00 Niphlod <[email protected]>: > > see the log to trace any DDos attempts (or stuck requests ) > > > On Friday, October 21, 2016 at 10:54:32 PM UTC+2, Wasim Baig wrote: > > Been using web2py for sometime now, thank you all for making life so easy. > > We use stock web2py src on debian 8, with Rocket and mysql and start them > in screen. > > Frequently my web2py process get stuck.
