Application showing "Connection Time Out" very often

Hi,


We have a web serveer running on Apache-Tomcat-6.0.32. For 2 months continuously, we noticed that the app on this server setup has been frequently sending out intermittent "Connection Time Out" issues.
On the OS side, I investigated a lot of things,



1) tcpdump : did not find anything suspicious (no large flooding of suspicious IP, etc)
2) In the apache access_log nothing suspicious either.
3) netstat -an, tulpn : No timeout/dead connection
4) telnet to port 80 is OK


Thus, my teammate concluded that it could be a bug in the tomcat version 6.0.32 itself. Is this possible/true? How can we confirm this?
We use "Uptime" as a monitoring tool, and it sends updates every 3 mins. Whereas other monitoring tools send alerts every 5 mins or more, and do not show the "Connection Time Out" problem.
Is "Uptime" an unstable monitoring tool?

NAME
Apache2::ConnectionUtil - Perl API for Apache connection utils Synopsis use Apache2::Connection (); use Apache2::ConnectionUtil (); use Apache2::RequestRec (); # grab the connection object; my $c = $r->connection; # share perl objects like $r->pnotes $old_val = $c->pnotes($key => $value); Description "Apache2::ConnectionUtil" provides the Apache connection record object utilities API. API
"Apache2::ConnectionUtil" provides the following functions and/or methods: "pnotes" Share Perl variables between requests over the lifetime of the connection. $old_val = $c->pnotes($key => $val); $val = $c->pnotes($key); $hash_ref = $c->pnotes(); obj: $c ( "Apache2::Connection object" ) opt arg1: $key ( string ) A key value opt arg2: $val ( SCALAR ) Any scalar value (e.g. a reference to an array) ret: (3 different possible values) if both, $key and $val are passed the previous value for $key is returned if such existed, otherwise undef is returned. if only $key is passed, the current value for the given key is returned. if no arguments are passed, a hash reference is returned, which can then be directly accessed without going through the "pnotes()" interface. since: 2.0.3 See ("Apache2::RequestUtil::pnotes") for the details of the "pnotes" method usage. The usage is identical except for a few differences. First is the use of $c instead of $r as the invocant. The second is that the the data persists for the lifetime of the connection instead of the lifetime of the request. If the connection is lost, so is the data stored in "pnotes".
