stream expression causing conflict issue in two iRules

Hello Team,

 

Need help in one of the issue which I am facing currently on our F5 environment. 1) I am having one VIP created where am having multiple iRules attached to it. 2) This is standard VIP with default stream profile, ssl profile, oneconnect profile applied on it. 3) I am having one iRule with stream expression in it and it was working fine till last week. 4) Now in last week I have attached one more iRule which is also having stream expression in it. 5) Now since last week I am seeing an issue where existing iRule's few functionality not working as expected.

 

Could you please let me know if I need to add any statement in the new or existing iRule not to conflict with each other.

 

BR, Ashish Takawale.

    Ashish,

     

    Without seeing the full list of iRules it may be useful to amend the priority of 1, or more, of the iRules to order them. As iRules are event based, actions within the same event can clash. You can add a priority to an event or iRule to ensure it's processed first.

     

    See this article for a fuller explanation Stacking iRules: A Modular Approach

     

    Hope this helps,
