Hi all
We have a strange issue. In the last days, we have some interrupts while we do calls, so while have a phone call, we can’t hear each others about 3-10 seconds. I start pinging our freepbx server and i got these while we have these interrupts:

The system is in a virtual machine, based on qemu. We have some other machines on the same host and when i ping the freePBX VM from another VM which resists on the same host, i have the same effect.
I follow the “top” and I saw, that the wait’s going up to 100% and the system is no longer responsible for a short moment. but never with a specific process on top.

iotop brings me not forward, there are no disk activity while the system hung in this short moment.
The interessting thing is, that this happens after 10-40 seconds every 5 minuten (xx:x0 or xx:x5)
