[comp.unix.aix] long delay

CALT@SLACVM.SLAC.STANFORD.EDU (06/17/91)

My machines here are running AIX 3.1.5. Sometimes when I try to log in, after
I type my username at the login prompt, it takes MINUTES (!) to get the
password prompt. As I checked, no one is running any big jobs on the machine.
And somtimes, I found even no one was currently logged on. As I recalled, it
occurs only after the installation of the 3005. Does anyone have the same
problem or similar?

Thanks in advance for any information!

If you have a large passwd file, there will be problems.  Call defect support
and request apar ix20305 for your level (3005).  You should see a REAL 
improvement in login time, if this was your problem in the first place.

This goes for anyone with a large /etc/passwd file, it really helps.

Yes!  She is not exaggerating.  After we used the patch, login time is 
shortened VERY much.  Our site, with > 9600 accounts, probably was the worst off
place using RISC 6000s a while back.

I posted about our site's long login delay problem about two months ago.  Julie
responded, together with my head SA, Dennis Micheal, a patch was worked out and
now even with over 9600 active accounts in our yp passwd file, our RISC 6000s DO
NOT have long login delay problems.  Most of the time it's as fast as other 
machines, only occationally it's bearably slow. 

If IBM keeps getting good people like Julie, man!  SUN/DEC/HP will be 
in trouble :-)

I post this to complement these nice and helpful IBM software develpers like 
Julie.  Good job.  Thanks.

I have a related problem.

The system prompts me to login. I enter a name, and instead of
prompting for a password it gives a login incorrect message and
reprompts with "login:". This comes and goes. I have never figured
it out sufficiently for a defect.

I'm still blushing....But on to more problems.  We've had this reported,
and usually it seems that it happens on the console, and something else
it grabbing the console and fighting with getty.  So, next time you 
see it, check out who has the console.  We're still trying to track it
down.  Let us know what you see, and if we get a fix, I'll let you 
know.
