Postmaster crashes

    Hi-

My php website interacts with a postrgres database, and every now and then,
postgres just seems to crash.  A simple restart of postmaster fixes the
problem, until it crashes again.  However, I have no idea EXACTLY when it
crashes (what the website users are doing at the time, if anything) and WHY.
If someone has any ideas as to why it might be crashing, or how I can find
out why, and what to do about it, I would appreciate the help.

Thanks,

Mike
