Hello community,
For some time now, I have noticed a random behavior on some of my OPNsense firewalls, running version 25.1.7 and above. Running on the VMware vSphere virtualization layer. In fact, randomly, a firewall completely freezes, I lose all web or SSH access, and the few times I can type the command, ps awwux, I see a kernel CPU at 100%, or sometimes python3 consuming 100% of the CPU.
Please, has anyone encountered this kind of issue?
We have started to identify some solutions, such as adding the following parameters:
net.isr.numthreads environment -1 Number of extant netisr threads.
net.isr.maxthreads boot-time -1 Use at most this many CPUs for netisr processing
net.isr.bindthreads boot-time 1 Bind netisr threads to CPUs.
net.isr.dispatch runtime deferred netisr dispatch policy
What do you think ?
Thank you in advance.
