Subject has anybody seen worker segfaults?
Date Tue, 19 Feb 2002 17:16:13 GMT
For some time some (but after 2.0.32), some tests I run have been
segfaulting around the time of a graceful restart.  Has anybody else
seen something like this?

[Tue Feb 19 10:31:43 2002] [notice] child pid 5367 exit signal Segmentation fault (11)

The test sends USR1 to the parent then sends in a request (and repeats
that cycle 6 or so times).

I'm not getting any core dumps from the segfaulting child (threads and
Linux :) ).  I need to spend more time looking into this, but first I
wondered if anybody else saw it.

RH 6.2:        segfaults as (barely) described above
Solaris 8:     no segfaults
AIX 4.3.3:     no segfaults
    (typical: the platforms where I can get a coredump pretty reliably
    don't have the problem :) )

Maybe this is a hint...  For a couple of the restart iterations,
worker on AIX logs this:

[crit] ap_queue_push failed with error code -1

Hmmm...
