Could you elaborate? I increased the soft limit in /etc/launchd.conf from 1024 to 2048 and restarted (installing 10.9.4 since I had to restart) I still don't get the build bar in GW. Did it address a different error for you? lsof reports mid-300s for Coherent processes and 400s for PA, which wasn't over to begin with.
I've set mine to 10240 and was able to play PTE 68079 with no coherent issues. /etc/launchd.conf limit maxfiles 10240 Switching over to 68253 now...
