Hi,
I am seeing too many TCP sockets open by tomcat on Oracle Linux 8:
java51798 root 6601u sock0,9 0t0 3959342 protocol:
TCPv6
I was running the same application on Linux 7.6 with the same apache-tomcat
version without seeing this issue. I saw that RedHat has
ache-tomcat"
(or anything else unique in that line)

are a mystery to me.
Could you redo a netstat as follows :
# netstat -p -a -n --inet6 | grep 130244
and can you also try this form of lsof :
# lsof -a -p 130244 -T s -i6
And finally (after copying the result of the above) : do you know how to
trigger a GC
(Garbage Collection) in your tomcat JV
that work. That's why I was asking if you had some method to do that.
(see : https://code.google.com/archive/p/jmxsh/)
But let's look at the lsof part first.

Hi,
Please indicate if there is any debug option and log that can trace sockets
open by tomcat to identify when and by which application function a socket is
open.
