what do these log entries mean?

[Suramya]

Hi Everyone,
My system emails me unmatched entries in my system logs. Today I got the following entries in the Log:


---------------- Connections (secure-log) Begin -------------------

**Unmatched Entries**
pam_console[1189]: Could not open lock file /var/run/console/suramya,
disallowing console access
pam_console[1199]: Could not open lock file /var/run/console/suramya,
disallowing console access
pam_console[1199]: Could not open lock file /var/run/console/suramya,
disallowing console access
pam_console[1236]: Could not open lock file /var/run/console/suramya,
disallowing console access
pam_console[1236]: Could not open lock file /var/run/console/suramya,
disallowing console access


and the second set is below:


--------------------- sendmail Begin ------------------------
252715 bytes transferred
16 messages sent

**Unmatched Entries**

h7JLJeE02596: Authentication-Warning: StarKnight.Suramya.com: suramya owned
process doing -bs
h7JLJeE02596: h7JLJfE02598: DSN: Service unavailable


what do these entries mean? I have tried searching on G4L but didn't get any usefull results.

Thanks for the help.
