We're trying to help Jim Jackson with an AIPS issue (<a href="https://helpdesk.nrao.edu/app/itdesk/ui/requests/228963000000970035/details" id="LPlnk220713">https://helpdesk.nrao.edu/app/itdesk/ui/requests/228963000000970035/details</a>) , we also tried a zoom
call and we are able to reproduce the issue, but we haven't been able to identify a root cause.</div>

originally, the issue presented itself in the machine ugd.gb.nrao.edu which has 128 GB of ram, we thought it could be that the data itself is too large. </div>

Given that this machine has been started yesterday, we don't think that rebooting would solve the problem.</div>
