then you have Mysql installed already. It won't be 4.1.10a most likely
4.0.x.
Just down load the 4.1.10a rpm and install it over the top of the

Don't tell me - you upgraded a PIII server to a PIV server?
The cache on the PIV is les than half the size of a PIII.
We've hit this problem with our own apps that by the way they operate cache
a lot of data. A PIII 1.4GHz will match a 2.4 GHz PIV.
