fast-cgi

[Bart van den Eijnden]

Huub,

maybe it is wiser to ask if other people have been experiencing memory leaks with Mapserver as a FastCGI?

I do remember Fernando warning me for memory leaks.

What are your settings for FastCgiConfig in the Apache httpd.conf?

Best regards,
Bart

Hi list (Bart),

i'm looking at a few thing concerning fastcgi and oracle spatial.

We're using OracleSpatial10g and fastcgi in a 4.5 compile, actually it
was compiled by Bart van den Eijnden :-) from recent sources
We found that every maprefresh uses more and more memory, it's never
released.
Maybe that this has got something to do with the included error

fastcgi is supposed to keep open connections, but i think it does
something more.
just now i stopped apache and memoryusage dropped from 2.5Gb to 300Mb ....

i found this in the archives
(http://mapserver.gis.umn.edu/wilma/mapserver-dev/0409/msg00149.html)
where the error is 'thrown'
