Linux CPU usage > 100%

[Pete]

Are you still seeing the errors from HSPI_rnbWeather.exe in your logs?

I have not seen any more errors since redoing the GPS coordinates here in rnb weather. I honestly do not know what it was causing the issue.

Disable the rnbWeather plugin for a bit and see what happens.

Same mono version as above listed here on Ubuntu 20.04.

Top 4 mono hitters in top here are:

model name : Intel(R) Pentium(R) CPU G4560 @ 3.50GHz

root@ICS-HS4:~# grep MemTotal /proc/meminfo
MemTotal: 16314596 kB

I did have weatherxml set to informational logging and saw it filling the logs so changed that setting to errors only.

Hello,

I as your Mono seems fine and was hoping zwolfpack was looking at this, please give a rundown of what if any scripts or running Node-RED (as with Node-RED and/or MQTT) may also cause this issue if disconnected from the server.
There also may be a script gone rouge. Check your routines in the Event setup and also compare to what's happening in the log.

Z-wave....???...hmm...

This is what I got from #fp -pf 491

UID PID PPID C STIME TTY TIME CMD
root 491 1 98 17:59 ? 00:39:57 /usr/bin/mono HSConsole.exe --lo

Mono version is:

Not an answer to your question, but can offer some interpretation.

Run this command

ps -fp 485

replacing the 485 with the PID from the leftmost column of the top output.

For me, the top output is

31823 root      20   0  263332 143276  42440 S   1.3   1.8   4250:44 (System)_23-Oct

and the ps output is

UID        PID  PPID  C STIME TTY          TIME CMD
root     31823     1 13 Oct23 ?        2-22:50:44 /usr/bin/mono HSConsole.exe --log

Note the process start time (STIME) of Oct23 corresponds to the value in the top output process label.

PS. you might find that the 'htop' command output is easier to read than that of 'top'.

Could be Mono related (type mono --version)
What version do you have and if at all run any scripts...


# htop

From time to time my HS4 Linux install slows to a crawl when I try to access certain screens (logfile in particular). When it happens and I check the Linux TOP command it shows (System)_xx-ABC is using more than 100% of CPU usage. In the output below, run today, it shows (System)_06-Nov but today's date is 11/13. The only remedy is to restart the system.

What could be causing the drain?
