Application cannot be launched error -10810
1) Other threads suggested deleting "/Library/Caches/com.apple.LaunchServices.xxx.csstore" and "~/Library/Preferences/com.apple.LaunchServices.plist" and repairing permissions. I did this to no avail.
2) In reviewing the console log, I found the following repeated almost without stop (though the actual pp cited changed, this was most common):
3/7/09 10:11:18 AM com.apple.launchd[1] (com.apple.airportd) fork() failed, will try again in one second: Resource temporarily unavailable
3/7/09 10:12:05 AM com.apple.RemoteDesktop.agent[216] LOG: could not launch checkpoint process (fork failure): Resource temporarily unavailable
3/7/09 10:22:04 AM com.apple.launchd[173] (com.apple.PubSub.Agent) fork() failed, will try again in one second: Resource temporarily unavailable
3/7/09 10:26:31 AM dotmacsyncclient[1562] SyncServer is unavailable: exception when connecting: connection timeout: did not receive reply
3) On doing more checking, I found my virusbarrier log also repeating perpetual messages:

4) I disabled real-time virus scanning on Virusbarrier and the problem went away. Console log has not registered in almost 30 mins now.
Any idea what might be going on. I have reported to Virusbarrier folks as well.
