Who Me Too'd this topic

Hi,

we're having an issue with 3050 very high cpu.new installed device and when checking dp file we see that ,

anyone can tell what can be cause this ? probably  ? Thanks.

panos 6.1.4

packet buffer is not high,

packet descriptor is not high

session count is normal

throughput is normal

packet rate is between 80000-100000 at problem time.
