Hi everybody,
I just want thank everybody for the information in this thread. We're
facing similar issues with java mapscript crashing the vm. Unfortunately
the application relies on the dynamic creation of layers and classes.
I tried the svn version this afternoon and it seems to be stable. No
more tomcat crashes till now. I will do some more testing on monday but
it looks like Umberto was right with expecting some good news :-)
Just in case this information is usefull: We're running our application
on Solaris 8 using Shapefiles, GDAL Raster (HFA) and WMS as datasources.
Tomcat is 5.0.28, JAVA is j2sdk1.4.2_11.
Regards,
Oliver

appreciate your help).
I say let's wait until Rodrigo tries out a rfc-24 enabled build,
frankly I am quite positive rfc-24 will fix his issues.

Umberto

Hi
Some developers (Umberto, Tamas) work on a solution of this problem.
As a workaround I made good experiences with

With "freeing manually" we made the Mapserver inside Tomcat quite stable.
Hope, this helps
