Yesterday we attempted to upgrade 2 of our clustered servers to 6.5 Service
Pack 4. We have also updated our non-clustered servers to 6.5.4. The
standalones presented no problems.

On clustered servers, when rebooting, an error message appeared attempting
to load perl.nlm but unable to because libperl.nlm must be unloaded. These
servers were then reverted back to NetWare 6.5.3 and the message went away.

This message only appeared on clustered servers, not on standalone servers.
I am of the belief that service pack 4 has something broken when it comes
to clustered servers. Has anyone tried this yet? Anyone else see the same
