This is a customer problem, I'll leave it to Guil to confirm.
The actual problem is that a patch to remove this function was
added to our RHEL3 version 2.4 kernel at about the same time it
was removed from from the 2.6 kernel. The removal of the
functionality from the 2.6 kernel had no effect since changes
to the VFS prevented this functionality from working "at all".
Unfortunately, as we know now, this isn't the case with the
2.4 kernel and the problem above was a direct result of the
So I recommend we revert the change.
The bad paths referred to above are, I believe, embedded in
system scripts and applications as search paths which cause
automount requests which cause lengthy delays waiting for
non-existent requests to fail and cannot be feasibly changed
I must have forgotten to set some flags. This is a current customer problem that
was not existent until we removed the negative cache setting.
Ian is right, the bad paths are in current apps that can't be easily changed.
