Check Metalink note 265769.1. It doesn’t list specific return codes but does aid in troubleshooting CRS reboots. Thanks.

I have not seen any documents on return codes that are mentioned in the log file. I remeber Gopal's book - I don't have accees to it right now - mentioning a few. But, is there a place where I can get a list of them. In my case, the cause is rc=11. {Receive failure with node 1 (*****01) , rc=11} Thanks, in advance.
