Please find the server.xml attached.
The real problem is I dont know where to look at.
-There are no error in logs or the linux sys logs.
- I cannot diagnose as the connector(443) does not even connect.

Tomcat 7 still crashes without acceptCount. I am wrong on this
assumption.
The response code is 504. It takes about 2 hours for this occur.
The last status in http-apr-443 (In Server status ) is :
Max threads: 5000
Seems high, as Chris says.
Current thread count: 249
Can you post your full server.xml please, inline and with all XML
comments/usernames/passwords removed.
Current thread busy: 2
Low.
Keeped alive sockets count: 40
Hmm? Where does that come from?
Max processing time: 300477 ms
Processing time: 8788.765 s
Seems low for 2 hours of operation. Where does that number come from?
Request count: 9223
Error count: 783
That's about 10%. What are those errors, exactly?
Bytes received: 0.22 MB
Bytes sent: 5.43 MB
Both of those seem low for 2 hours of operation.
What is your application/server doing?
p
What happens if you configure your HTTPS connector with fewer max
threads, say, 50? Does the connector lock-up more quickly? What does
your load profile look like? Is this observable in a testing
environment or only in production? If you could set up a simple jmeter
test against a test webapp, that would be ideal for trying to debug
this issue.
If you switch to NIO or BIO connector, does Tomcat become more stable,
or do you experience the same phenomenon?
