After installing patches 104331-04 and 103612-33, nis_cachemgr(1M) failed to start. The symptoms are as follows during the reboot:
Sep 11 16:34:00 nis_cachemgr: Error in reading NIS cold start file : '/var/nis/NIS_COLD_START'
This error is a timing problem. Put a sleep(1) before the NIS+ initialization in /etc/init.d/rpc, after rpc.bind has been started. rpc.bind is slow initializing and needs a few extra seconds before nis_cachemgr(1M) takes effect.
