Hi Satya, Inline..

We will try it for sure in this week. Regarding our scenario for example: we have 4 workers. All the 4 workers can create ACLs and also can process data. During high load of data and create ACLs, we are seeing this crash. There are NO delete of ACLs done in the test. BV: I guess, even if it is mere creation, for a brief instant between creation of 2 ACE, under an ACL, an ‘implicit deny’(drop packet) is assumed in data path. In scaled operations, in a multi worker scenario, a race condition could arise.. No? -- Regards, Balaji. Thanks & Regards, Murthy As I mentioned earlier, after putting a lock around the "add acl" and "rulematch acl" code, issue got solved.
