freeze problems with latest kernel 4.19.37-v7+ ?

Thu May 02, 2019 8:48 pm

Hi,

i have alot of problems (Raspberry Pi 3b+ 4.19.37-v7+) with freezing networking connections during a ssh session or when I copy a file from windows to a samba share on the pi. The file transfer and the ssh session freezed completely for a couple of seconds.

My other Rasperrry Pi 3b didn't has this kind of problems. Everything works flawlessly. It has an older kernel version 4.14.98-v7+ installed.

I don't have a clue whats going on with the pi and why the network stucks, network cable, switch an setup is configured right. What can I do ?

regards,
Frank

I've checked the processes and saw that the collectd daemon consumes a lot of cpu time. average systemload is greater 1.5. I stopped collect daemon and the average system load drops from > 1.6 to 0 :shock: I believe that something is wrong with the collectd process. It cannot be normal that one process consumes near all system ressources from the pi. System is running nomally since I stopped this daemon.

regards,
Frank

yesterday I made a downgrade from 4.19.37-v7+ to 4.14.98-v7+ but with no luck, freeze problems stayed. Only when I stopped the collectd daemon , my raspberrypi3b+ comes back to normal operation. collectd seems buggy and consumps nearly 100 % of cpu power.
