What kind of rule was about to be created? How does the PR look like? Is it reproducible only on service chain scenarios?

Following are the steps which we did when we saw the issue.

    Create a tenant(member).
    Create 4 classifiers as following
        icmp : icmp classifier
        udp: udp bi-directional
        tcp: tcp bi-directional
        redirect_class: classifier with no protocol and port(Created this from CLI)
        tcp80: tcp port 90, bi-directional
    Create 4 allow actions(allow1, allow2, allow3, allow4) and 1 redirect action with FW service chain spec(to insert FW in E-W)
    Create 5 rules as following
        pr1: icmp+allow1
        pr2: tcp+allow2
        pr3: udp+allow3
        pr4: redirect_class+allow4
        pr5: tcp80+ redirect action
    Created PRS 'prs1' using rules pr1, pr2, pr3, pr4 and pr5.
    Create consumer and provider PTG to use the above PRS 'prs1'. FW service was inserted between the consumer and provider groups.
    Create another 4 classifiers as following:
        icmp1: icmp classifier
        tcp1: tcp classifier
        udp1: udp classifier
        redirect_class1: classifier with no protocol and port (created from CLI)
    Create 4 allow actions(allow5, allow6, allow7, allow8)
    Create 3 policy rules as following:
        pr6: tcp1+allow5
        pr7: udp1+allow7
        pr8: icmp1+allow6
    Now tried creating another allow rule using redirect_class1 classifier and allow8 action. Observed the policy rule create issue.

Note: After sometime, when tried adding the same rule again, the rule creation was successful.
