Please enter a FULL description of your problem:
------------------------------------------------

When running the following query I get the following stack trace. The
problem seems to only happen after running for hours and sometimes a couple
days. The query is usually executed every 2 minutes or so. The actual
value of the 'response type' seems to be relatively random.

It is running from a tomcat jsp/servlet using the jdbc driver.

Execute: select id, reverse_name, ssn, address1, address2, address3,
street1, street2, city, state
, zip1, zip2, phone, work_phone, fax, email from nap where id = -1;

Please describe a way to repeat the problem. Please try to provide a
concise reproducible example, if at all possible:

The problem seems to happen randomly. We can't reproduce it at will. We
are using connection pooling. Perhaps a problem with more than one thread
using the same connection???
