hi all…
i have an netbsd instance on amazon's ec2 ws. it has pretty standard php+mysql+httpd installation on it. everything was build from pkgs. today a lot of people who were accessing it got the "connection reset" message. many times.
my https error log looks like this:

i tried to attach a current httpd process to gdb but gdb dies with this:
/usr/src/external/gpl3/gdb/dist/gdb/thread.c:81: internal-error: inferior_thread: Assertion `tp' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
i was hoping somebody here can point in me in the right direction to figure out what exactly is happening and how can i get rid off it..
the instance is 6.0 NetBSD 6.0 (XEN3_DOMU) amd64
thanks..
