Temporarly high CPU usage on 2200s after upgrade to 10.4.1 HF6

Hello,

 

we recently upgraded to 10.4.1 HF6 on our 2200s cluster and expiriencing temporarly high cpu load on the active box currently.

 

Normaly the cpu usage is about 20% per core. If our problem occurs, the cpu usage wents to 100% per core. This load is produced by the tmm process.

 

If I delete the persistent records with "delete ltm persistence persist-records" the cpu load drops immediately and after ~a day the problem occurs again.

 

For now i do not have an idea, what the box is doing which is causing this load. Do you have any ideas, where i could search?

 

Basicly we do not have any special configuration on this box. Its basicly some ssl termination, nat, and basic irules for header insertion.

 

Regards Alexander

    HF6 has a bug it causes a different issue with me (both units are going active-standby-active-standby-.... and so on), I prefer to go with 11.6.0-HF3

    I received a message from F5 last weekend that while an engineering HF release was available to address the tmm restart issue upon request with F5 Support, an official HF release for v11.4.1 and v11.5.1 would be available in one week.

      Hello Mahmoud, we updated to 11.6.0 last night, and for now it seams to be okay. We'll keep the systems monitored for the next days. Regards Alexander
