Hi Van, I don't know where you got autofs-4.1.0-3, but we don't support it in any of our distributions. We could take autofs out of the loop and try again, so we can at least see if the problem may strictly be NFS related. Would you mind trying that? If that doesn't elicit the problem, then we'll see about getting you closer to a supported autofs configuration. Thanks! Jeff Jeff, Do we have a reason to believe that autofs may be at fault here? The RPC message above leads Oracle and myself to believe otherwise. If we have a good reason to believe autofs may be an issue or any evidence that points that way, we'd like to know before trying to duplicate with a different autofs. It doesn't look to be autofs at first glance. That's partly why I suggested taking autofs out of the loop. Please give it a try. Jeff, Turning off autofs on these systems will essentially make them useless. Autofs4 is used *heavily* on them as an integral part of the environment. Can we please begin debugging this problem as they're hitting it often. Regarding autofs, if you can give a good reason why it's an autofs issue, I'll be happy to treat it as such, but otherwise taking autofs out of the loop isn't really an option :/ Ok, that's too bad. I will talk with our NFS maintainer and see if we can narrow things down based on your bug report. It appears it could be a memory fragmentation problem. Would it be possible to get an AltSysRq-m output? No problem. I'll ask our guys to do that next time they hit the issue (shouldn't be long). Where do we stand on this BUG? Please verify that this is still a problem with the latest RHEL3-U3 kernel. We have made VM changes to help deal with the memory fragmentation issue that are included in U3.

patch to failover to ZONE_DMA in case of fragmentation
Sorry, I should have pushed harder on this.
The fallback issue is not resolved in 17.EL, I've attached the
one liner patch to resolve this issue...

Van, I think this problem has ben fixed in RHEL3-U4, can you verify this so we can close this bug? Larry From what I've seen, this is fixed with the reduced-size ACLs for NFS in U4. Is there a bug number we can reference here for this? Then this bug can be closed. Cheers, Greg Thanks for the info, Greg. I'm closing this as a dup of bug 118839. *** This bug has been marked as a duplicate of 118839 *** An errata has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on the solution and/or where to find the updated files, please follow the link below.
