Looks like you ran this on the client. Sorry, Ian, I should have been more
specific. You need to modify the rpc_debug file on the server.

I tried this on the server but it's pretty crippling (the server is
quite weedy, 300MHz K3 or something).
I'll leave it logging overnight since things should be pretty quiet (and
that's often when the problem occurs) but if there's a less aggressive
setting than 256 but which would still be useful I could leave it on
permanently until the problem happens.
Marriages are made in heaven and consummated on earth.
