Description of problem:
We are observing OVN_contoller container consuming high memory and crashing.
This is observed on multiple computes nodes with similar behavior.
Version-Release number of selected component (if applicable):
How reproducible:
The issued occurred randomly on quite a few hypervisors.
Steps to Reproduce:
1. ovn-controller container memory usage went very high (600G+)
2. A core dump file generated on /var directory, which consumed all available space on that directory
3. ovn-controller container couldn't be restarted as /var is already full
4. ovn-controller container was restarted after the core dump file removed from /var
Actual results: ovn-controller crashes
Expected results: default ovn behavior
