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>SoftResourceLimits</key> <dict> <key>Core</key> <integer>10000000000</integer> <key>CPU</key> <integer>10000000000</integer> <key>Data</key> <integer>10000000000</integer> <key>FileSize</key> <integer>10000000000</integer> <key>MemoryLock</key> <integer>10000000000</integer> <key>NumberOfFiles</key> <integer>8192</integer> <key>NumberofProcesses</key> <integer>150</integer> <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, Greeg
