System Configuration
---------------------
Architecture: Intel(R) Xeon(TM) CPU 2.80GHz
Operating System: Debian/GNU Linux i686 GNU/Linux
PostgreSQL version: (PostgreSQL) 7.4.7
Compiler used: gcc 3.3.6
Problem description
---------------------
Usually our program dumps core several times a day, but the reason is
unknown. All I know from the core file is the lines below.
during PQexec(db->conn, query) it dumps core.
Should it happen due to a connection problem between the pgsql server
and our program? What could be the resolution to avoid the coredumps?
