IV99521: INIT DAEMON WRITES EXTRANEOUS ENTRIES TO WTMP APPLIES TO AIX 7200-03

APAR status

• Closed as program error.

Error description

• If an inittab process has been switched from 'respawn'
  mode to another mode like 'once' with the chitab
   command, init will write an entry to wtmp once per
   minute regarding this process.
  If auditing is configured a certain way, turning on
  auditing may cause these writes to happen much quicker
  (multiple times per second). Likewise, any other
  activity that might send SIGCHLD to the init daemon
  would cause the writes to happen more frequently.
  

Local fix

Problem summary

• If an inittab process has been switched from 'respawn' to
  'once' and the process is killed, init writes entry of this
  process into wtmp file once per every minute thereby flooding
  the file with so many entries
  

Problem conclusion

• Needs to clean the process table entry for this process whose
  mode is chnaged from respawn to other mode after trhe process
  is killed. i.e remove the dead process entry which prevents the
  writing of the init into wtmp file
  

Temporary fix
