High CPU USG60w - zylogd

elkrust

Hi,

I have a USG60w running firmware 4.35 and CPU 1 & 2 are running at 99%, crashing occasionally.

I did a Router# debug system show cpu status

CPU utilization: 98 % (system: 47 %, user: 18 %, irq: 0 %, softirq 33 %)

CPU utilization (1 minute): 99 % (system: 47 %, user: 18 %, irq: 0 %, softirq 34 %)

CPU utilization (5 minute): 98 % (system: 44 %, user: 16 %, irq: 0 %, softirq 38 %)

then...

Router# debug system ps. This line seems a bit out of place :

 1149  1 zylogd     root  ?    19 0 51.6 0.2 Ssl 27112 2144 18044 6778 14:27:13  03:02:49 01:34:27 /usr/sbin/zylogd

The zylogd process seems to be consuming 51.6% of the CPU.

Is this normal? Can someone point me in the right direction about zylogd?

Thanks in advance

Darrin

Hello @elkrust,

are you on 4.35(AAKZ.2)?

Please see if this is still occuring when using the latest weekly firmware:

https://support.zyxel.eu/hc/en-us/articles/360005438274-Weekly-Firmware-Support-Version-Lab-Version

Backup your configuration file beforehand.

I am writing you a personal message if the weekly firmware is not helping.

Best regards

Lukas
