Mapscript ,Mono, Apache and Linux : a great story

Wed Jun 14 14:00:35 PDT 2006

Hi,

It would be helpful if you could you file a bug describing the steps to
reproduce this problem (including code sample and map file if necessary).

I guess you have called a getFeature on a postgis layer which is generally
not uncommon and have been tested many times.

However i am not sure about the application environment and the threading
issues in this case.

Thanks,

Tamas Szekeres

Subject: [UMN_MAPSERVER-USERS] Mapscript ,Mono, Apache and Linux : a great
story

HI

I'm developping a web site using Mono (1.1.13) Apache (2.0.54) MApscript
(4.8.3). I'm using Vs2003 to develop and linux as deployement platform.

All works well with windows but on linux i get the folowing error in th
error_log apache file and the web server shutdowns.

Any help well be appreciated. I don't know what to do 

regards

Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.
