terminating connection because of crash of another server process

Hello

I have a postgres database version 8.1.11, in an Ubuntu Server 6.10.

Some days before, I have a hardware failure in my server, and after recover
the database I get some problems with tables and I had to REINDEX some of
its.
But now, doing any actions in the database server (for example: SELECT *
from my_table), I continue getting the follow error:

"""
WARNING: terminating connection because of crash of another server process
DETAIL: The postmaster has commanded this server process to roll back the
current transaction and exit, because another server process exited
abnormally and possibly corrupted shared memory.
HINT: In a moment you should be able to reconnect to the database and
repeat your command.
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Succeeded.
"""

Any help, to solve this or an idea about anything I must check, will be
appreciated.

The log of my server shows the follow messages over and over:
