Super Large /var/log files

thorpey01 · Post by **thorpey01** » Thu 31. Mar 2016, 13:02

I have been using the CharDev drivers and the PCAN Basic API to write Python code to send and receive CAN messages.

How do I turn off logging of CAN messages to /var/log/ kern.log and syslog etc
I am seeing massive log files being produced .. one is 50GB ! .. i look in the logs and they are full of all the CAN messages I am looking at.

can i just delete these massive log files with SUDO? How do i stop them logging again.. ?
best regards,

Nicholas

Hi,

which driver version do you use and with which settings did you compile it? Please send the output of cat /proc/pcan to see more details

regards

Michael

I've done a bit of research on this .. it could be a bug with Ubuntu.. possible solutions are to turn off ACPI in the BIOS.. I can't beleive Ubuntu could just let these log files grow to such large files as 50 GB .. and fill up your hardrive so that your PC is inoperable..

Hello,

Could you please give us an extract of these logs (last 50 lines, for example), something like:

Code: Select all

$ dmesg | tail -n 50

We'll see what are the reasons of these logs,

Thanks.

Stéphane

I'm having the exact same problem too. kernel and syslog chocked full of pcan transaction information.
