There is most likely a security feature in your backup application that is locking the library.

I have been running Backup Exec 9.0 for about 6 months and this is the first time I have encoutred error, no config changes have been made. How can I resolve it? Reboot MSL?

Re: MSL 5026 mail slot error

You should confirm the setting on the console menu:

Press Menu > Library Options > Scroll down to "Mail Slot Mode"

If it is set incorrectly, you can change it at the console by:

Menu > Edit Options > Library > Scroll down to "Mail Slot Access"

Take a look here for the manual:

Re: MSL 5026 mail slot error

Rebooting the MSL will always force a reserve to be released. Some application running on a host connected to the library issued a reserve command to cause the library to get in that state in the first place. BE will issue those if configured to do so and it may be that it lost the reservation and forgot to release it before allowing the unload.

If the problem re-occurs power-cycling the MSL again wills till clear the reservation but it won't do anything to actually fix the cause.
