Subject Re: [users@httpd] Apache getting stuck with all workers in a BUSY_READ state
Date Wed, 16 Jun 2010 13:33:55 GMT
Thanks for the suggestion, but unfortunately I've tried that - truss
in this case is attaching post whatever it's blocking on (so I just
see it sleeping), and I haven't yet waited out the problem to see what
happens when/if whatever's blocking times out. Any other ideas?
