[mapguide-users] WMS with MapGuide OS 4 Beta 1 on Ubuntu 22.04

[Daniel Knoop]

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&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
