Hi,

                                                                                
                                                                                
                                          

 The problem seems to be caused by the build process. I have the same problem 
with my installation (Ubuntu 22.04 and Apache)

Hi Gorden,

 

thanks for your reply. But changing this parameter seems do change nothing.

I think php is not affected by this request?!? It is a direct call to 
mapagent.fcgi. And the buffer overflow log message appears only, if I do WMS or 
WFS requests against mapagent.fcgi.

 

 

Mit freundlichen Grüßen

In the PHP.INI the output buffering is quite now.  you can try increasing it: 

 

output_buffering = 4096 (default)

Hi List,

 

I’ve installed MapGuide OS 4.0 Beta 1 on a fresh Ubuntu 22.04 Server. Most 
seems to work, but I can’t get WMS running.

If I try to open the capabilities document, I get “Error: Server returned 
nothing (no headers, no data)” in my client.

Digging around in the logfiles, I’ve found in 
/usr/local/mapguideopensource-4.0.0/webserverextensions/apache2/logs/error_log:

 

[Fri Jan 12 08:36:22.292425 2024] [core:notice] [pid 4624:tid 140102563568576] 
AH00051: child pid 5007 exit signal Abort (6), possible coredump in 
/usr/local/mapguideopensource-4.0.0/webserverextensions/apache2

*** buffer overflow detected ***: terminated

[Fri Jan 12 08:42:55.758679 2024] [core:notice] [pid 4624:tid 140102563568576] 
AH00051: child pid 5471 exit signal Abort (6), possible coredump in 
/usr/local/mapguideopensource-4.0.0/webserverextensions/apache2

*** buffer overflow detected ***: terminated

 

This appears every time, I request the capabilities document.

http://server:8008/mapguide/mapagent/mapagent.fcgi?service=wms 
<http://server:8008/mapguide/mapagent/mapagent.fcgi?service=wms&request=getcapabilities&version=1.3.0>
 &request=getcapabilities&version=1.3.0

 

The same installation (all default, using apache2) on Windows is fine.

 

Is there any hint, how to get running WMS with MapGuide on Linux?

 

Thanks, 

 

 

Mit freundlichen Grüßen 

Daniel Knoop
