Sometime's when logging into our Ubuntu server we get "Signature not found in user keyring" other times we don't.  Does this pose any kind of security issue, or any other issues?

Not a security issue.

This message provides notification some resource (likely an encrypted filesystem) can't be currently accessed.

If this is intermittent, likely somehow the required authentication is occurring, then dropping, then reoccurring in background somehow.

Thanks David, now I've got another question how can I configure alerts to be sent to certain users/machines in the event the audit log becomes full or reaches the set threshold?  We're in a disconnected environment so email isn't an option, what other methods would accomplish this?

Best to open other questions (one topic/question) for additional questions.

Quick answer...

1) How can I configure alerts to be sent to certain users/machines in the event the audit log becomes full or reaches the set threshold?

You'll use email.

Another option, is to use your Desktop notification system. Where you have a CRON job which does an ssh into your machine periodically, then pops up a desktop notification when file system usage exceeds some threshold.

2) We're in a disconnected environment so email isn't an option, what other methods would accomplish this?

In a disconnected (no Internet connectivity), there is no way to accomplish what you're asking.

You must have some way for the box to notify you or some way for you to poll the box.

Any method will require some sort of connectivity to the box.

Again, this is best asked in another question, so you can better describe your runtime environment.
