Hello,
I have a problem with voipfirewalld. It takes always ~100% one CPU-core even, when no one talk and it doesn’t matter if Irqbalanced is running or not.
There are total of 2 cores with 2GB RAM (VMware ESXi 6.0).
Other issues are sometimes interrupted connections or right after call: “Hello? I hear nothing! Hello?”.
Last System Update vor two days. Last fwconsole ma upgradeall - today.

I can’t found nothing interesting in LOGs.
The only interesting thing would be ‘pstack’:

When I stop the firewall (fwconsole firewall stop) the CPU-usage goes down to about 10%.
What and where can the problem be? What can I try, that the CPU usage goes down without having to turn off the firewall?
