Hi, I'm just trying to get the resource limits working with launchd and a plist. Whatever I try I get a segmentation fault.

I've tried with an empty dict:

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>TEST</string> <key>OnDemand</key> <false/> <key>ProgramArguments</key> <array> <string>/bin/ls</string> </array>

<key>SoftResourceLimits</key> <dict> </dict>

</dict> </plist>

And also with some dummy values:

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>TEST</string> <key>OnDemand</key> <false/> <key>ProgramArguments</key> <array> <string>/bin/ls</string> </array>

<key>ResidentSetSize</key> <integer>100000000</integer>

<key>Stack</key> <integer>10000</integer> </dict>

</dict> </plist>

Do I at least have the format correct? I couldn't find any examples with google to work from.

Cheers,

No, sorry, can't wait until Leopard. I want to use the resource limits for a program currently running on a production server. What is thing that is easily confused? I have tried both soft/hard limits -- that is not what you mean, is it? Is the implementation actually broken? I thought somebody here could just clarify the form for setting the limits.

Ok, thanks for the help. On 9-Jul-07, at 1:43 PM, Dave Zarzycki wrote:

Syntactically, what you added to your property list is correct. The bug in launchd (fixed in Leopard) is difficult to explain. I think the most pragmatic thing to do on a Tiger based system is to do is wrap the daemon in a quick shell script and have it adjust the resource limit you want. For example:

#!/bin/sh

ulimit -c 0

exec /usr/sbin/serverd
