System information & parts of the Xorg log file

When using system with more than 1 virtual terminal running x the Xorg log
files grow so large (>8 G) the the system quits responding.

The problem can take 30 to 60 minutes before appearing.

This problem has not occured when running just 1 virtual terminal.

this is a snippet from the log where the problem starts:


(EE) Warning: attempting to log data in a signal unsafe manner while in signal
context.
Please update to check inSignalContext and/or use LogMessageVerbSigSafe() or
ErrorFSigSafe().
The offending log format message is:

(WW) Warned 3 times about sigsafe logging. Will be quiet now.
