an FYI for others. this behavior happened exactly as described above regarding several of my boxes. i ended up finding out that the file /etc/issue had thousands of lines of carriage returns. obviously removing the file and creating a new one resolve the issue. fun times trying to figure that little gem out Smilie

Another different cause of similar behavior can be the /usr/sbin/quota command which is part of the /etc/profile script taking an very long time to proceed.

Thank you for the feedback.

I have checked and found neither /etc/issue exist nor quota has been set in this server.

I have executed "truss -a logname" and found that there is some difference when compared with another server's output.

Server with logname returning null value

The problem server doesn't proceed beyond /dev/syscon..

Any input would be appreciated!

Sure. These were examples of different root causes of similar issue. Yours has already been found and it is just the login script used is bogus. Logname isn't required to return a value so the script should take that into account.

You might test logname status and use a different approach to get the username like this:
Code:
logname=`logname`
logname=${logname:-`/usr/xpg4/bin/id -un`}

or simply use
Code:
/usr/xpg4/bin/id -un

in the first place.

Well, if logname isn't required, how does the environment variable
LOGNAME get the value?

We have another server with similar configuration ( replica ) which works fine.There, it does return a value.

Anyways, these are my unresolved doubts.
I would try out your workaround, jlliagre Smilie.
Thank you for your invaluable assistance.Smilie
