Thanks, Marco.
I just tried that...the command completed in a split second i.e.
immediately. I rebooted, started octave in an xterm, and issued the
command "plot(1:5,1:5)". The error is still present, but seems to
have shifted to another oct/dll:
octave:1> plot(1:5,1:5)
5 [main] octave-3.4.2 3804 child_info_fork::abort: address
space needed by 'cellfun.oct' (00340000) is already occupied
error: popen2: process creation failed -- Resource temporarily unavailable
error: called from:
error: /usr/share/octave/3.4.2/m/plot/__gnuplot_open_stream__.m
at line 30, column 44
error: /usr/share/octave/3.4.2/m/plot/__gnuplot_drawnow__.m at
line 72, column 19
I'd welcome any further suggestions.
