[web2py] Re: Communication error when saving in admin web interface

2019-11-07 Thread Davidiam
Thanks for your reply.  I have also had this when testing locally but only 
when debugging the save process.  I noticed that the save failed when I 
stepped through the code, most likely due to a timeout.
In our case, it seems to be worse the longer the edit session stays open as 
I mentioned in my first post.  

Kind Regards,
David

As a work-around we are now using a local editor mapped to the server drive 
and that seems to not have these issues.
I would still like to see this solved (longer timeout?) but we have a 
work-around for the moment.

Regards,
David

I get this kind of error occasionally.   Where it may be weeks between 
errors.  But I'm running Windows desktop, not server, using Rocket instead 
of IIS, and Chrome for the browser.  The webserver involved is only 
accessed from the local machine.

In my case, it seems the request times out (not the session), and that can 
happen when Chrome is doing a lot of browser cache related accesses to 
Rocket (as best as I can tell; the activity meter on the web2py "console 
GUI" is almost continuously spiking even though I stop clicking on things; 
it can persist indefinitely).  My treatment of these symptoms is to close 
the browser window, wait for things to quiet down, and reopen the window.  
(It may be possible to just close tabs, but I often have a dozen tabs 
pointing at my applications or the admin pages.  Using the browser menu to 
select "clear cache" doesn't seem to help.)

I have also seen the error when there is a path or permission issue, IIRC, 
but that is unlikely to explain your symptoms.

Try a different browser to see if you get the same errors.  Monitor the 
browser's background accesses to see if they spike during the session.

Good luck!
