Summary: Postmaster hangs under load

System Configuration
--------------------
Operating System : Solaris SunOS 5.5

PostgreSQL version : 6.4.2

Compiler used : egcs 1.1

Hardware:
---------

Versions of other tools:
------------------------
gmake 3.74
flex

Problem Description:
--------------------
I run a number of processes which are adding records to a database using the C++ interface. Then, run a few processes which read a couple of records from the database (same table). After a while (an indeterminate amount of time), all the processes hang. I have to kill them all and the postmaster process and restart it all to get it running again. This is very consistent. I can supply my sample code. It happens on Linux with the same exact code. the only difference is that I am using Postgres version 6.3.2 on Linux. I am in the process of evaluating Postgres to be used for a ver important project. If this cannot be fixed, I will have to abandon Postgres as a possible candidate.
