Chester Knapp updated QPID-7355:
--------------------------------
Description:
We use the qpid-cpp-client-0.34-6.el7.x86_64 driver in our project.
I'm noticing a lot of open files (to dead TCP sockets) that are being held open
and it appears that they are qpid related (this project don't open any TCP
connections other than what the qpid client handles).
Is there perhaps something I need to do on the underlying
qpid::messaging::Connection other than call close() in order for the file
descriptor to be closed?
Here's some representative output from lsof:
{code}
#lsof | grep "^cloud" | grep -v ESTABLISHED | grep TCP | head -n 1
COMMAND PID TID USER FD TYPE DEVICE SIZE/OFF
NODE NAME
cloudisti 6387 6404 root 55u sock 0,6 0t0
66423 protocol: TCP
{code}
{code}
# lsof | grep "^cloud" | grep -v ESTABLISHED | grep TCP | wc -l
192
{code}
For what its worth, we don't see this issue in another of our applications,
which uses a driver built from the qpid-cpp-0.34-rc branch.
