I'm trying to VNC into an OSX 10.4.11 box from Vista using RealVNC and TightVNC. I can connect successfully, but after a minute or so my VNC window freezes completely, while on the Mac the AppleVncServer process starts eating up huge amounts of RAM (100Mb +) and CPU (40-50%) - but the Mac doesn't freeze. When this happens no-one can VNC in anymore until the AppleVncServer process is restarted.
I have trawled through all the available options on the VNC clients I'm using and I don't see anything obvious that would cause this behaviour. I'd be grateful for any insights into this.
UPDATE: After more troubleshooting it seems this happens only when I to a copy on Vista. As soon as a copy operation is performed VNC freezes up. Note that copy paste inside VNC works fine....
