Yes,  the PIDTYPE_MAX enum is equal  to 4.  Setting 'plen' to 4 seems to work.
So, it seems like a problem with get_array_length.

I will get you the dump/vmlinux files as soon as I can upload it
someplace (yousendit is acting up).
 
 

Thanks -- the download is underway (*very* slowly)...

In the meantime, can you remove the "plen = 4" hack,
and then do the following:

  $ crash -d7 vmlinux-2.6.16.13-xen test.core

At the very end, just prior to the crash session ending, you should
see the gdb request for pid_hash, which should show something
like this:

GDB IN: command: 15 (GNU_GET_SYMBOL_TYPE)
buf: 0
fp: 31d072d8c0 flags: 8  (GNU_RETURN_ON_ERROR)

What do you see when you do that?

Thanks,

I'll let you know what I find out...

Thanks again,
