[SSI-devel] SSI-1.9 oops child_reaper for process under gdb
|
From: Roger T. <rog...@gm...> - 2005-12-06 09:33:16

Laura,
I got an oops exiting from gdb while attached to check_bacula which had
segfaulted. I eventually fixed the bug in check_bacula, but take a look at
the oops below. child_reaper was waiting for check_bacula which is in E
state. It looks like pvproc got corrupted.
I'll leave this in kdb until tomorrow just in case I left out something.
Roger
