HI All, I'm currently facing an issue with respect to huge pages memory vs ACL Trie operation.
Problem Statement: I am doing some ACL TRIE build operations and I can see hugepages_rsvd count is increasing and they are not available for use. As a result, the real available/free huge pages reduces over time and at some point, the trie build fails due to insufficient huge pages. For addition of just 30 ACL rules, 60 huge pages are going to reserved and 11 ( 136-125) huge pages are getting used up. No Rules: HugePages_Total: 1234 HugePages_Free: 136 HugePages_Rsvd: 0 HugePages_Surp: 0 with 30 acl rules: HugePages_Total: 1234 HugePages_Free: 125 HugePages_Rsvd: 60 Could you please help us provide some more insights into it . * Is this the expected behavior and if yes, what is the reason? * Is there any optimization on this area? * How can we know the worst case memory requirement for ACL Trie? Thanks in advance.
