CPU goes 100% - Process temain ted

[sebasnqn]

Hello mates! How are you all?

   We're having issues in our FW; perhaps one of you had this problem before.

FW is an open server, Version 81.10 with JHF T130; it has hyperthreading enabled  and is running as proxy.

Every working day seen past few weeks, the CPU  goes to 100% for several minutes. We checked the process and the temain ted seems to be taking all the stars.

There are a few elephant connections but can't be accelerated because of FW been used as proxy I think.

I've checked the affinity for temain, and seems to be attached to all the CPU available.

But, if I do "tecli show affinity" the result is 

Command: root->show->affinity
error: unable to retrieve process affinity

If I check the management to see logs of the IPS blade, there is nothing there, probably because FW its suffering on 100% load.

I've no idea where else to look or what to do here; help would be really appreciate.

Thanks in advanced!

Does cprestart or reboot help?

Hello Andy,

     Thanks for replying.

We did not restart the FW; I could try it tomorrow. After those 20 to 40 minutes of 100% load, goes like "normally".

I know one client who had this problem and went away after they upgraded to R81.20. I cant recall now what jumbo they installed, but this was few months back, probably April or May.

Ok, it's an option!

      We've thought that and it's scheduled to do this weekend; we'll see if it helps!

Thanks!

Hi @sebasnqn 

If we talk about "Elephant Flows"  consider to user SecureXL Fast Accelerator" 

https://support.checkpoint.com/results/sk/sk156672

It would help a lot.

Hi Sir,

  Thanks for replying.

We've a few rules activated, but no hits on them. I think related to the proxy usage of the firewall.

Thanks though!

That also makes sense to me.

ted is "Threat Emulation" not IPS.

Traffic cannot be accelerated with SecureXL when the gateway used as an explicit proxy.
