I tried parsing a gigantic XML file and I ended up running out of virtual memory. The OS put all my applications on pause and gave me a screen to shutdown applications to free more space. I killed the XML parsing application and now have tons of space but I can't resume my paused applications anymore. What should I do?

Find your paused app's process ID (using either Activity Monitor or ps -ax | grep ), then issue it the CONT signal using "kill" in the terminal (don't worry, "kill" is misnamed, it just sends a signal to an app - it's called kill because the default signal is QUIT)

% ps -ax | grep Safari
  461 ??        61:22.30 /Applications/Safari.app/Contents/MacOS/Safari -psn_0_180268
% kill -CONT 461
%

thanks for the hint! but it lead me into this similar solution: simply using killall -CONT Safari - feel free to add this to your answer! ;) – Cawas Apr 13 '11 at 15:46
Is there an easy way to find out which processes have been paused? – asmeurer May 24 at 23:04

This article mentions an app called 'pauser' which might help.
