[Test Case] Deploy openstack environment; create large number of virtual networks and routers. OVS will start to error with 'Too many open files' [Regression Potential] Minimal - we're just increasing the NOFILE limit via the systemd service definition. [Original Bug Report] When there are a large number of routers and dhcp agents on a host, we see a syslog error repeated: "hostname ovs-vswitchd: ovs|1762125|netlink_socket|ERR|fcntl: Too many open files" If I check the number of filehandles owned by the pid for "ovs- vswitchd unix:/var/run/openvswitch/db.sock" I see close to/at 65535 files. If I then run the following, we double the limit and (in our case) saw the count rise to >80000: prlimit -p $pid --nofile=131070 We need to be able to: - monitor via nrpe, if the process is running short on filehandles - configure the limit so we have the option to not run out. Currently, if I restart the process, we'll lose this setting. Needless to say, openvswitch running out of filehandles causes all manner of problems for services which use it.
