The logstdinlimit variable places a limit on the number of bytes from the standard input stream that Privilege Management for Unix and Linux writes, at a time, to the I/O log. When data appears on any of the other channels, the this variable is reset to zero. A value of 0 has the effect of placing no limit on the amount of stdin data sent to the I/O log. To turn off the logging of standard input data to the I/O log, set the logstdin variable to false.

logstdinlimit = number;
