[mapguide-users] RE: Studio Enterprise and Web Studio Cannot Connect Randomly

[Andy Morsell]

To increase the XP IIS connection limit from 10 to 40 (which has worked fine
on my development laptop), see this page at the MGOS Wiki.

Connect Randomly


Hi Chris,
 
IIS under Windows XP has a hard coded concurrent connection limit - 10
connections I think.  Internet Explorer and the embedded  IE control within
Studio may spin up that many connections to serve a map.  If you get back a
bunch of 403 errors then you are probably hitting this limit.
 
There is also an occassional cannot connect to URL error when a FastCGI
Mapagent process has shutdown and another one has not started up yet.
Typically, this is a single error.  The error "wakes up the agent" and a
second connection attempt should go through successfully.
 
I have also seen rare cases where the Apache/IIS FastCGI link to
Mapagent.exe and php-cgi.exe does not initialize successfully.  This
effectively locks out the Web Extensions.  In these cases stopping Apache or
IIS, manually killing all of the mapagent.exe and php-cgi.exe process, and
restarting Apache or IIS generally corrects the problem.  As an added
measure of insurance, stopping and restarting MapGuide Server can be
performed along with the Apache/IIS restart.
 
 
Hopefully this will help,
 
Trevor

Randomly, I have noticed that Studio Enterprise gives errors like cannot
connect to URL. Web Studio bombs and spits out a whole message box with page
code... basically same error. I have fixed the issue with a reboot and
sometimes a uninstall/reinstall of the extensions. Using IIS/PHP
installation options on XP as my development and testing machine. Why does
this happen?
