description |
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. |
[Impact]
OpenStack environments running large numbers of routers and dhcp agents on a single host can hit the NOFILES limit in OVS, resulting in broken operation of virtual networking.
[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.
