But it only does it if I've got ~/bin in my path. If I type 'which ..' I get ~/bin/.. as the result. This also happens if I just execute '/', ie. the root directory. The panic that the kernel throws is: panic: ufs_lock : recursive lock not excepted, pid: ... This is quite scary, because we have users on this machine with no root access, but they're able to halt our machine whenever they want to. I guess this would be very scary for an ISP offering shell accounts. My setup is: FreeBSD Billy.poptart.org 2.2-STABLE FreeBSD 2.2-STABLE #0: Sat Aug 2 00:17:32 BST 1997 scot@Billy.poptart.org:/usr/src/sys/compile/IDE i386 The shell in question is bash v2.00.0(0)-release Any ideas? Is this fixed in a later release of the OS? Thanks in advance.
