Thanks Marius - I agree and have added locks around file reads and
writes - will see how it works...
One follow up question though: I was under the impression that MX locks
file and variables reads/writes automatically.
And indeed, Page 187 of "CFML Reference" says "In the ColdFusion
Administrator, Server section, the Locking page sets locking options
according to scope..."
I don't see any such section - does anyone know what they are talking
about? I thought I was pretty familiar with the adminterface but don't
see this anywhere...

While locking the applications doesn't hurt, I think you should lock the
cffile process (with named locks) when writing to the log file. This way
you
are single threading access to the file.
