diskimages-helper problem when mounting on a mac

[bassmit]

Hi guys,

Ive got a program that runs on Mac OS 10.5.8. The program runs a continuous cycle where it mounts an image, installs a browser plugin and unmounts the image again. If I leave this program running I eventually end up in a situation where I get the following error "fork: resource temporarily unavailable". In the activity monitor I can see that several hundreds of processes called diskimages-helper are running. Does anyone know why this happens and how I can avoid it? Below are the commands I use during one cycle of the program.

// First I remove the plugin
rm -rf "/Library/Internet Plug-Ins/my.plugin"

// If the mount exists I unmount it
hdiutil unmount [mount] -force

// If that doesnt work I detach the device
hdiutil detach [device] -force

// Then I mount the image
hdiutil mount [image]

// I install the plugin
installer -package [package] -target /"

// Unmount
hdiutil unmount [mount] -force

// And if necessary detach
hdiutil detach [device] -force

Thanks, Bas
