Hello VPP experts, I am observing crash while configuring classify tables more than 1135. Have tried with heap size 1G and 4G. This issue is reproducible on both *VPP v21.06* and *22.02-rc0* Classify table command configured: *classify table mask l3 ip4 src dst

() In show memory main-heap I can see free memory is in GB, after configuring classify table at index 1130. But still it seems memory is exhausted, that is causing this crash. No traffic is running. This crash is just while configuring more than 1134 classify tables. Please suggest here, how this crash can be fixed. Regards, Vijay
