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?
