Well, these make it clear that you've got some pretty big chunks of
nonstandard code in the backend, so my first thought is that there's a
memory-clobber bug somewhere in that.
I'm not sure what you mean by 'nonstandard code,' could you expand on
that?
The traces include code from /usr/local/lib/libgrid.so and
/usr/local/lib/libpcmsrv.so ... I don't know what those are,
but I'm quite sure they are not invoked by a standard Postgres build.
I also find it suggestive that they appear to have been written in C++
... we've seen problems before from trying to link C++ code into the
backend, because it tends to bring along its own incompatible ideas
about how to do error recovery and memory management.
The libpcmsrv is a library for looking up miles, vendor provided. I'll
have to check on the other one, it may be related to the same package.
Thanks for the heads up on C++ code.
It seems we may have located a memory problem in a library that is used
throughout our code, thus, we are looking into this at this time.
Thanks again.
