SierraWireless using lots of CPU & filling up disk space (EM7455 on X1C5, T570, ...)

2018-06-07, 8:36 AM

Hi

This is a problem I've had once before - I seemed to fix it previously, but it's back (possibly after the Windows 10 build 1803 update a couple of weeks ago, which I think is like a fresh install).

 

The symptoms are:

* I have 25% CPU (fan on continuously) running Service Host: Radio Management Service

* Something is writing full speed to logs in: C:\ProgramData\Sierra Wireless\Logs\Sensor_Location Archived Logs - I get a  new 100MB logfile every 20 seconds!!!

 

The log files are called, e.g. Sensor_Location-SWLOCRM 2018-06-06_09.10.38.Part407, and just have this one line repeated:

Jun-07 09:18:51.063 86919.703880 000010c0 i : cRadioManager::RemoveInstance - checking radio Instance {27A89091-C3E5-4ED7-8219-44FA25475EFF}
Jun-07 09:18:51.063 86919.704009 000010c0 i : cRadioManager::RemoveInstance - checking radio Instance {27A89091-C3E5-4ED7-8219-44FA25475EFF}
Jun-07 09:18:51.063 86919.704052 000010c0 i : cRadioManager::RemoveInstance - checking radio Instance {27A89091-C3E5-4ED7-8219-44FA25475EFF}

 

Last time I had this issue (5 mins before I was due to give a presentation... not stressful at all... :p ) I thought I just disabled the Mobile Broadband *Sierra Wireless EM7455 Qualcomm Snapdragon X7 LTE-A) adapter in Network Connections temporarily, but that doesn't seem to have stopped the logging - perhaps I rebooted too (which I think will stop it for a while).

 

I regularly run Lenovo Vantage software updates and am fully up-to-date. From Device Manager my driver seems to be (though it is disabled now:

  • Provider: Microsoft
  • Date: 10/04/2018
  • Version: 10.0.17134.1

(is that right that it's a MS driver, not Lenovo or Sierra Wireless?)

 

Any ideas? (note: it's interesting to read https://forums.lenovo.com/t5/ThinkPad-X-Series-Laptops/SierraWireless-EM7455-in-X1c5-is-Lenovo-going-to-fix-its-poor/td-p/3716748 and talking about firmware on the card - I don't know whether that might be related)

 

TIA!

Simon

All,

 

The command I previously posted to stop tracing was missing an element. Run Command Prompt as administrator and enter the below command; hopefully this stops the log generation.

 

netsh mbn set tracing mode=no

Sierra Wireless - log - Full disk - T570

2018-05-31, 13:10 PM

Sierra Wireless make logs. Logs have 136gb and destroys the SSD disk. Because it completely fills him. Computers have current drivers.
The problem is on all T570 computers with windows 10, 64x. We need a quick fix.

Re: Sierra Wireless - log - Full disk - T570

2018-06-08, 8:21 AM

I have the same problem with my T570 (20JWS06E00), Windows 10 (1803), 64bit.

At the location C:\ProgramData\Sierra Wireless\Logs\Sensor_Location Archived Logs there are tons of txt files with the only information e.g: Jun-08 10:15:20.815 924094.302868 00000ef8 i :   cRadioManager::RemoveInstance - checking radio Instance {82F2359C-7C8D-4644-8EE1-B79052E754C7}

each file has the size 97.657 KB.

If I do not shutdown my laptop, there is no free space on my harddisk  on the next day.
In the moment I can only delete the folder periodically.

Another workaround might be to deny write permissions on that folder...

Re: SierraWireless using lots of CPU & filling up disk space (EM7455 on X1C5, T570, ...)

(sorry not to reply sooner - my forum notifications seem to have stopped :( )

 

My workaround was to disable the Sierra Wireless adapter in Control Panel->Network and Internet->Network Connections but I still think I needed to reboot too. I've had mine disabled since I posted it and haven't had any reoccurance, but need to enable it again now as I need 4G to work.

 

I can't tell if it's a Sierra Wireless issue or a Windows networking issue (looking at the messages).
