Actually it is a case of "no news is good news" at this end. I have been running with the patches and memsync on the test servers since the last patch was posted. I also went out and bought four ethernet cards to match the ones in the live servers, and installed those so the setup is now far closer to the ones which fail - the importnat difference being that I now have gigabit between the machines, instead of 10meg - as it fails under oad I theorised that having the slower cards in the test rig was masking the problem by throttling the rate data was being sent to the remote machine. WIll continue to test here for a while - the live setup is perfectly stable under fullsync, but when the patches are MFC'd to 9-STABLE I will upgrade the boxes and give it another try under memsync. thanks for the investigation and patches!, -pete.
