tomcat not accepting requests
Hello, my config
Ubuntu 9.10 Server AMD 64 RAM 512
Tomcat 6 running with native libraries and XMX=400M
Maybe once a day, or each 2 days tomcat stops handling requests.
Error 101 (net::ERR_CONNECTION_RESET): Unknown error at the browser.
1. Service is UP
2. telnet to 80 port works OK
3. netstat -a is listening @ por 80 perfectly
4. nothing in the logs. NOTHING. (logs as default installation)
I checked and I'm not being DOS attacked.

nop, but I will read about these tools and use them next time.
do you have idea what it can be ? is really weird. Is not heavy load,
because I saw it die 11pm with 1 session opened at the server.
