Re: Problem with PostgreSQL 9.2.7 and make check on AIX 7.1

Hello,
so far:

- The switch to POSIX semaphores do not solve the problem...
- It's not CPU dependent, the problem does show on Power 5 and Power 7+
- The problem does show on AIX 7.1 (at least on Technology Level 3)
- The problem does not show on AIX 6.1
- If I send a SIGINT manually to the backend process nothing happens.

My next steps:

- Instrument the SIGALRM handler
- Instrument the SIGINT handler

Bye
Rainer
