Hi Massimo,
Good Morning. And sorry for my poor English.
Q1) when you saying it hangs are your trying from a new incognito window or
from the same browser? It may be a session lock not a freeze.
Ans) Whenever sever freezes/hanged. We try to access our pages from
different browser bit still get no response. At that time server never
accept any request. The only option is to restart server.
Q2) are using apache? Don't it has memory issues. Use Nginx
Ans) As I already explained that I am running web2py using python command
as mentioned below:. Not usng ang any server as apache/Nginx, etc.
python web2py.py -a <mypassword> -c 138c3b68d25b8a7d.crt -k
keyfile.key --ca-cert gd_bundle-g2-g1.crt -i <IP> -p <port>
Q3) do you have processes that may take a lot of time? consider adding
session.forget() at the beginning of those actions and/or move the
computation to a background task
Ans) I am not using session.forget(), as I maintain session expire after
20min. But 20 min is enough for any process, which perform heavy task.
Q4) are you using sqlite? It does serialize all writes and locks the DB in
the process. Have you tried postgresql?
Q5) if you are using postgresql, have you checked the database logs?
Ans 4 & 5) I am using mysql database server only. Initially I think that
large data process might create problem, but same table with same data
works fine with PHP and JSF/Icefaces application, server takes time to
process, but never be down like web2py.
Please let me know, I am running web2py directly using python is the
problem, if it is, let me know the best server either apache/Nginx that can
I use?.
Or Can increase memory used by python at runtime?.
Please help me.
Regards
Narendra Kumar
