Re: Network Driver Cannot Open Network Device!!

Hi, I think you are somehow running out of some system resource. However, I'm not sure it is due to kernel parameters. As you are on Solaris, I assume you use TLI (protocol ontlitcp in sqlhosts file). TLI errno 8 simpy means "System error" - which is not very much help. Errno 12 means "Not enough space". So maybe you are somewhere running out of space - which gets cleared up by a reboot ?
