I've never seen that here. I have three NIS servers though, so there has never been a case when all NIS resources were unavailable. Usually what I see in the logs are: Mar 12 13:52:13 ypbind[113]: NIS server [10.0.0.11] for domain not responding Mar 12 13:52:13 ypbind[113]: NIS server [10.0.0.89] for domain OK Was it ypbind that was hogging all the file descriptors, or what, I wonder? -- Dan Nelson dnelson@allantgroup.com
