Hi, Thanks again for your answer Thomas.
I have seen that issue report and I am using mapserver latest version (6.0.2 (which is what you meant? or is there an actual 6.2 somewhere) It does indeed keep working if i reference a good map and hammer F5. Although: when i for instance call a wrong mapfile and hammer that it will also kill the processes. Is there a workaround for this? Otherwise people can just execute denial of service attacks on my mapserver. We're already using nginx for static file hosting. It would be great if i could get a production ready mapserver environment there as well. 2012/5/11 thomas bonfort <[email protected]> > You might want to have a look at > https://github.com/mapserver/mapserver/issues/3099 > > tl;dr > - mapserver fastcgi calls exit() when running in an error condition, > which causes some fastcgi spawning managers to have issues > - mapserver 6.2 (current git master) has been refactored to greatly > minimize the exit() occurences (basically only on memory allocation > errors) > > -- > thomas > > On Fri, May 11, 2012 at 10:42 AM, Peter Maes <[email protected]> wrote: > > Hello, > > > > I'm trying to run mapserver on nginx (fastcgi), but after 2 days booked > > little success. > > > > 1.
