Zlatomir I do not have lots of experience with this OGR layer type. In order to narrow it down you need to analyze error logs, mainly PHP and Apache. There is a FAQ item for this
http://svn.pmapper.net/trac/wiki/FaqDebugging If I check the identify function with Firebug, 2 call types cause "500 Internal server error" /incphp/xajax/x_info.php and /incphp/xajax/x_load.php?...&zoom_type=zoompoint This is usually related to - a PHP error (manifested in your PHP error log), so this has to be analyzed further in the PHP code - a segmentation fault of apache (logged in apaches's "error.log") which is normally related to hidden bugs of MapScript, and need to be checked with simplified scripts, usually only Mapserver developers will be able to help you in this case. This type of error appeared especially in Mapscript/Mapserver v6 Armin On 21/01/2012 14:19, Zlatomir Dimitrov wrote: > Dear Armin, > Dear Pmapper - Users! > > I am writing to all of You, because of a very strange problem occurred > recently. > > Preface: > We developed a service that is so called “Riskwatch” > (http://bsdi.asde-bg.org/riskwatch_en.php) and it is a system > (aggregator), which monitors continuously, filter and extract disaster > news happened over the territory of Bulgaria in 20 - Bulgarian news > sites.
