OSX FMS 5.5 won't stop

[dvalley]

We are running a cross platform solution of FM 5-6. We have four Mac G4 (400mhz- 1.25Ghz) towers running OS 10.3 and FMS 5.5 and one P4 Server running WIn 2000 Server and FMS 5.5. The problem is with the Macs. While they perform adequately (albeit slow)under OSX, when we try to stop the server using FM Server Config, the dialog box says it is shutting down (and that it may take a few minutes, the server never stops. It can take half an hour or so before we must force quit. It is consistant across all of the Macs. Why is this?
