After installing and using some newer Adobe programs, like Photoshop CS4 or newer versions of Acrobat, you may notice a flood of messages in /var/log/system.log reading kernel: unknown SIGSEGV code 0. These are caused by a broken FLEXnet licensing server; Adobe knows about the problem and says it is "normal." There is a relatively simple way to fix it.
Save the following file in /Library/LaunchAgents as com.18james.killFNPL.plist:
#! /bin/sh
# kills Adobe FNPLicensing Service to prevent log clutter
# ron@doofus, 14 Dec 2008
sleep 5
pid=`ps -axc | grep " FNPLicensingServ" | awk '{print $1}'`
[ $pid ] && kill $pid
exit 0
Finally, run these commands in Terminal:
$ sudo chmod +x /usr/sbin/killFNPL
$ cd /Library/LaunchAgents
$ sudo launchctl load -w ./com.18james.killFNPL.plist
This works by setting launchd to watch a data file that the FlexNET licensing server modifies each time it authorizes the use of the Adobe product. When the file changes, it sends a sigterm signal to the licensing server. End of bogus error messages in the log and CPU load of the FlexNet licensing server.
