Would you mind collecting all of the *.test output files for the tests that failed and send them to me in a tarball, such as: cd tcl/tests find . -name *.test -type f | xargs tar cvfj ns-2-diffs.tbz2 and send me the ns-2-diffs.tbz2 file? Thanks, Tom Here you are, I exactly execuuted your command, but not sure if it has all the outputs that we want (i.e., for tests: test-all-tcpLinux, test-all-tcpHighspeed, test-all-red and test-all-cbq. So please let me know if you need other outputs, Thanks, Behnaz
