However, from songbird's original post: >>>> i have the following set in my /etc/sysctl.conf: >>>> >>>> # core file location and file name format >>>> kernel.core_pattern=/crash/core.%u.%E.%p That appears to be a kernel parameter which defines the path and filename of the core file. I imagine that this was set in order to be able to specify a filename other than the default, with relevant information about the dumping process (and avoiding the problem of multiple such files overwriting one another), and that the syntax of the kernel parameter in question is such that you have to specify the full path to the file. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
