Hi Stuart, Thanks for the stack dump. Dave Glowacki came up with a candidate fix, which is now in the visad_src-2.0.jar and visad.jar files at: ftp://ftp.ssec.wisc.edu/pub/visad-2.0/untested/ If this doesn't work, you might try putting a delay of a couple seconds before the call to ActionImpl.stopThreadPool(). Please let us know if you continue to have problems. Good luck, Bill
