Wanproxy Crashes

Hi Juli,

 Just checking to see if you've had time to look through the
code yet.

 Regards.

This looks to be from a different function,
but that's okay. I'll
read through the code tomorrow and see if I can find
the problem that
way.

Thanks for your patience,
Juli.

(Note to self:
really need an ASSERT variant that takes a LogHandle so
I can tell what
instance of a base class is tripping the assertion.)

Would
it be possible for you to run wanproxy under gdb on the client
and send
'backtrace' output when it crashes?

Thank you!

Juli.

Hi,

I applied the patch and complied
wanproxy. It worked ok for a while then
it
crashed. I have pasted toe
output below. Does it have anything to do
with
the operating system I am
running it on?

Thanks for your patience.

Best Regards.

Hi Julius,

I haven't
even compile-tested this patch to epoll support, but could
you try it (or
whatever variant you can get to compile) and report
back?

Please help.

Also, does wanproxy handle
multiple tcp connections simultaneously?

Thanks.
