I'm sure there are others. So since you are running fastcgi, it is the responsibility of the fastcgi parent process to clean up dead child processes. It is likely that it is busy because you are doing load testing or there is some subtle issue that is occurring. If you are getting good responses from mapserver, you probably do not need to worry about it unless you are getting tons of them.<br>
<br>
If you are using apache, I believe there is a parameter that you can set for fastcgi processes which will let them die after N requests. This should clean those up and apache will spawn a new process if needed to replace the that died.<br>

Hi all,<br>
<br>
I'm getting a lot of<br>
<br>
27098 x 20 0 0 0 0 Z 1 0.0 0:00.03 mapserv <defunct><br>
27104 x 20 0 0 0 0 Z 1 0.0 0:00.03 mapserv <defunct><br>
<br>
while load testing mapserver. Is there any way I can go about checking<br>
out why this is happening? Especially when doing concurrency tests it<br>
seems to go sideways.<br>
<br>
Currently i'm using :<br>
<br>
MapServer version 5.6.5 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP<br>
OUTPUT=SWF OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=AGG SUPPORTS=FREETYPE<br>
SUPPORTS=ICONV SUPPORTS=FRIBIDI SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT<br>
SUPPORTS=WFS_SERVER SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER<br>
SUPPORTS=SOS_SERVER SUPPORTS=FASTCGI SUPPORTS=THREADS SUPPORTS=GEOS<br>
SUPPORTS=RGBA_PNG INPUT=EPPL7 INPUT=POSTGIS INPUT=OGR INPUT=GDAL<br>
INPUT=SHAPEFILE<br>
<br>
using FastCGI/Lighty.<br>
<br>
Do note that the mapfile itself seems to be fine, since it does render<br>
content when i'm the single user using it.<br>
<br>
Thanks for your expert insight :D.<br>
