[IRCServices] issues with updating operserv databases

[Nick Gawronski]

Hi, I am trying to save my data bases from version 5.0 as I still have it
running in memory but have 5.1pre2 installed on hard drive.  When I run
/msg operserv update I get the following message, version 5.1 is installed
where version 5.0 is installed so don't know why I am getting this
message, what should I do?
*operserv*> update
-OperServ- Updating databases...
*** Global -- from services.nickgawronski.com: Warning: Unable to lock
