/var/log/messages files on Security Gateway repeatedly show - 'stopping debug messages for the next X seconds' and 'lost Y debug messages'
Symptoms
  • /var/log/messages files on Security Gateway repeatedly show:

    FW-1: stopping debug messages for the next X seconds
    FW-1: lost Y debug messages

    where X and Y are integer numbers
Cause

These message are printed when:

  1. the debugging buffer was not allocated with 'fw ctl debug -buf SIZE' command (and is set to the default 50 kilobytes)
  2. the amount of debug messages exceeds the limits determined by values of kernel parameter 'fw_kdprintf_limit' and of kernel parameter 'fw_kdprintf_limit_time'


'fw_kdprintf_limit' indicates how many kernel debug messages (default - 30 ; zero - disables the limit) can be printed in 'fw_kdprintf_limit_time' seconds (default - 60 ; zero - disables the limit).
