Re: [Postgres-xc-general] failed to find proc - increasing numProcs

[Aaron J. <aja...@re...>]

It appears that problem is a compiler optimization issue.  I narrowed the issue down to the loop at the end of the ProcArrayRemove method.  I'm not entirely sure why, but the compiler generated code that evaluates the test block of the loop improperly.  Since changing the compiler options, the problem has been resolved.

I forgot to mention that if I injected a context switch (sleep(0) did the trick as did an elog statement) during the test in the ProcArrayRemove, that it no longer failed.  Hopefully that will help in understanding the reasons why that may have triggered the ProcArrayRemove to succeed.
