[Rabbit-dev] Stack overflow error

[Mindaugas Žakšauskas]

Has anybody ever spotted this? It happens during the runtime on some
particular URL, still haven't traced which exactly.

I'm using rabbit 4.6.

I have not seen such things in quite a while, but I do not really see
anything in the 4.7 ChangeLog that indicates that it is fixed. There is
the pipeline buffer overwrite, but I am not sure if that affects this
issue. If you could find any page where it happen reliably I will be
very happy.

I'm using rabbit 4.6.

Is it possible to upgrade? the pipeline buffer overwrite can probably
cause many odd problems.

I might try but this has only happened twice in half a year or so.
Will try to put more effort into digging if this comes up again.

I will upgrade eventually (need to do some tests before), however you
mentioned that 4.7 doesn't touch anything related, does it?

Thanks for ideas anyway, will post more info if/when available.
