HP Tru64 UNIX Release Notes for Version 5.1B-5 (AA-RVGEE-TE, March 2009)

3.4.12 SIA sialog Use Limitation Required
The Security Integration Architecture (SIA) sialog logging process is intended only
for use in debugging SIA problems. It should not be enabled for extended periods of
time. Doing so can cause login delays or other problems.
Use the audit , not the sialog process
, subsystem to monitor authentications on the system.
To disable sialog debug logging, delete the /var/adm/sialog file. For more
information, see the sialog(4) and sia_log(3) reference pages and the Tru64 UNIX Security
Programming document.
