Where should reviewer start? background context? - List any dependencies that are required for this change. --> Summary: Increase our VM threshold to support deploy large scale vms. Fixes # (issue) 32767670 ### Type of change <!-- - Fill x for your type of change. - e.g. - [x] Bug fix --> - [ ] Bug fix - [ ] Testbed and Framework(new/improvement) - [ ] New Test case - [ ] Skipped for non-supported platforms - [ ] Test case improvement ### Back port request - [ ] 202012 - [ ] 202205 - [ ] 202305 - [ ] 202311 - [ ] 202405 - [ ] 202411 ### Approach #### What is the motivation for this PR? Without this change, ceos VM will abnormally terminate ProcMgr.service which led to BGP down. During this time I noticed dmesg ``` [4351605.348948] neighbour: ndisc_cache: neighbor table overflow! [4352518.918103] neighbour: ndisc_cache: neighbor table overflow! [4353433.024687] neighbour: ndisc_cache: neighbor table overflow! [4353433.024717] neighbour: ndisc_cache: neighbor table overflow! [4353737.315904] neighbour: ndisc_cache: neighbor table overflow! ``` Which indicate the neighbor arp cache table be out of entry. Adjusting here make the VM more stable on large scale. #### How did you do it? #### How did you verify/test it? #### Any platform specific information? #### Supported testbed topology if it's a new test case? ### Documentation <!-- (If it's a new feature, new test case) Did you update documentation/Wiki relevant to your implementation? Link to the wiki page? -->
