The indexing server is generating errors in the Windows Event Logs
when it performs a full crawl. After some searching on the web I found
the above (subject line) command that I need to run.
Being our live environment I need to ensure that it would not do any
damage. The command
stsadm -o sync deleteolddatabases 5
Lists a few GUID values but I do not know what databases names they
refer to.
