it looks like there are 2 problems here. if i remove everything java from my work (32-bit) computer, the problem goes away (no more lockups). that got rid of /usr/share/binfmts/jar, which i assume was the source of the lockups. that's definitely a security issue because an unprivileged user can launch a very effective DOS with just a couple of shells.
unfortunately, the same didn't work for my 64-bit computer at home. i still have the same (original) problem. to sum up, i removed everything mono and java so now the only thing in binfmts is 'python2.5', but the problem is still there. i'm assuming this is still a bash problem because of the error message. ** Changed in: bash (Ubuntu) Sourcepackagename: None => bash -- shell scripts cannot run from bash https://bugs.launchpad.net/bugs/299690 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
