Dear All,
I have an exception that is littering my catalina.out. I see about 7000 of
these on a normal day (server handles about 25 requests per second). It is this
precise stack trace always. I have some other exceptions, but this one is the
main headache I have today.
Tomcat 7.0.30
openjdk version "1.7.0_25"
FreeBSD 9.1-STABLE
My questions:
1) What might be causing this?
2) What other information do you need to help shed some light on this problem?
3) How can I found out if this is happening from specific IP addresses maybe?
4) Any queues that might be overflowing? I have acceptCount 1024 and
kern.ipc.somaxconn 1024, which should be plenty, right?
5) Any other steps I can take to dive deeper?
