MapServer 4.10.1 Memory Leak still exists

[Tamas Szekeres]

David,

Would you file a bug report and send your mapfile and shape data and
the input data of the test you've executed? I will try to locate the
problem then.  With the information you have provided I'm not really
sure whether the problem is related to the mapserver core, the C#
interface or the ASP.NET execution environment.

The bug submission page for mapserver is:
http://trac.osgeo.org/mapserver/newticket

As prowling in the code I've also found potential leakage issues like
described at:
http://trac.osgeo.org/mapserver/ticket/1545
and there are also some other bug reports related to the memory problems.

Anyway it would be quite an useful to isolate the portion of the code
causing this particular issue.

Best regards,

Tamas
