DrayTek ISDN Vigor128 Drivers Hard Disk Usage

DrayTek has acknowleged a bug in the recently released version 4.0 of their ISDN Vigor128 drivers, available in both Mac OS X 10.1.5 and 10.2.x flavors. Daniel Jardine explains the problem and offers a temporary workaround:

"After installing the 10.2.x drivers, I noticed constant hard-drive activity whenever I was online. After much searching, I identified the problem as a constant stream of messages being written to /var/log/system.log at a rate of over 20 per second. In the terminal, typing 'cd /var/log/' followed by 'tail -f system.log' shows these messages being written whenever data is received or transmitted over the ISDN modem. Here is a temporary workaround:

"In the Terminal type:

  • cd /etc/
  • sudo pico syslog.conf
  • (enter sudo password)

"The second line of the syslog.conf file should read: *.notice;*.info;authpriv,remoteauth,ftp.none;kern.debug;mail.crit /var/log/system.log

"I simply commented out this whole line (place a "#" character at the start) and then saved the file. However, perhaps someone can work out which particular message format is the culprit, and simply remove it from the list of messages logged."

DrayTek says updated drivers without the problem are on the way.
