Hi All,
I am running Tomcat 3.1 in stand-alone mode on AIX 4.3.3 using
IBM JDK1.2. My servlets connect to an Oracle database and
forward to a jsp to display the results. Of late I have had
flaky behaviour from this operation.
Problem 1.
Every now and this request causes a SIGSEGV and core dump.
========= BEGIN excerpt from javacore... ==============
SIGSEGV received at 2 in . Processing terminated.

Problem 2.
This request takes too long. I click the stop button on the
Netscape browser and it just sits there waiting. I check on
the server and 'netstat -a | grep <port>' reveals a connection
in LISTEN status and another in CLOSE_WAIT status. However,
from this point on no other connection from any client works.
(It takes inordinately long. I waited ten minutes with no
result other than CPU going to 100% on the client side.)
I have to re-start the server before I can do anything else.
This is really bugging me. Please help.
