You are right! I don't set the LIBUSB_DEBUG variable on the production machines anymore. Some weeks ago, at the very beginning of our investigation, I had set the LIBUSB_DEBUG variable to 3 on the production machines, but it had no impact on the error logging. There were no log entries of warning or info messages after the crash happened. The only result of this action was a poor response time of the machines.
BUT, on the test machine I set LIBUSB_DEBUG to 4. So, in my opinion, we won't get more data from the production machines than the crash log on the test machine already provides! > On 2012.08.09 22:25, Pete Batard wrote: > To confirm that the timerfd_settime() is the call that's causing us an > issue, can you please try to set your production servers to at least > output warning messages?

I'll give it a last try and set LIBUSB_DEBUG to 2. > On 2012.08.09 22:25, Pete Batard wrote: > I'll try to push a patch to make sure we get errno displayed.

Please consider that I'll have to replace every change (recompiled lib) on more than 25 machines! ========= Regards Sebastian ========= ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
