Hello,
I use php 4.2.1 as stand-alone binary to proceed batch file conversions
with exec() and other utilites (ie mapserver, shapelib and others)
The binary is compiled with postgresql and ming support.
The amount of files to convert is over 10,000.
Each file needs 8 (height) exec() to be converted.
After lots of loops (throusands but it varies), i obtain the error
message :
<br />
<b>Warning</b>: Unable to fork
[/usr/local/tdf/www/src/mapserver_3.5/shp2img -m
/usr/local/tdf/www/src/swfs/temp.map -o

When i ran a #top in the same time, i saw that pid numbers of executed
programs increases during execution of the script, and the exec did not
reuse pid numbers already used in the same script if the loop is too
quick (when the script converts small shapefiles).
the highest number i saw was
The total number of processes on the system was not over 71 in the same
time.
Any idea ?
