This is to address an issue where it was observed that SAI operations sometime may take a very long to time complete (over 45ms). It was determined that the ALPM distributed thread was causing this issue.
The fix is to disable this debug thread that has no functional purpose.
Preliminary tests looks fine. BGP neighbors were all up with proper routes programmed
interfaces are all up
Manually ran the fib test cases on 7050CX3 (TD3), TD2, TH, TH2, and TH3 based platforms and
thy all passed.
Note: the testing was done over 20201230 image and are porting this change to master branch.
No need to port this to 20201230 branch as a separate PR was already done for that branch. (#9190)
this PR is created to port the changes made by (#9199) but could not be cherry picked directly to 202106 branch.
Why I did it
7050 S4Q31 mmu configuration is missing ALPM configurations, causing not enough memory reserved for routes. Orchagent crashes on a nightly testbed with 6400 route entries.
How I did it
Add the missing ALPM configurations.
How to verify it
Load the configuration on testbed and verified new configuration exists and no more crash.
