ssh-agent's resident set size increase 8K after each authentication

ssh-agent's resident set size increase 8K after each authentication

Post by Cellinc » Sun, 05 Jan 2003 01:18:10



I've setup ssh-agent to do scp and rsync jobs in crontab. The system
complained swap space was run out several days ago. And I notice that
ssh-agent has used around 10M RSS (resident set size).  I restarted
ssh-agent, everything seemed back to normal, the RSS was about 1M. But today
ssh-agent became a "large" process again.
I found after each authentication, ( each time a scp job is finished) the
RSS of ssh-agent increase 8K. so it can increase to 10M again in a few days.
It's really weird, because ssh-agent has run on the system for more than 1
year and this problem never happened before. I didn't do any changes to the
system(or at least I don't remember I did). So what cause the resident size
increase and what should I do?

Any help will be appreciated !

My own agent experience the same thing, it is on OS390, what is your
machine platform?

1. xterm: huge process size and resident set size

Solaris 9 FCS with Recommended patches through approx. October 2002;
CDE.

What causes an xterm to hang for on the order of a minute when I
resize it? The system is banging noisily on the disk the whole time. I
have approx. 720 MB of free swap out of a GB, 320 MB RAM, and / is
less than 50% full. This is an Ultra 10/ 300 MHz, but I have seen
similar behavior on many other systems and at other installations, so
I'm convinced that it's either an xterm or a Solaris issue.

The scroll-back log is not even that large (although I always start my
xterms with "-sl 10000" (ten thousand lines max scrollback).

I see that the xterm process size is 145M and RSS is 134M, so that
seems to be the immediate cause of the performance issue. The question
then becomes, what could cause those numbers to be so large?, because
most of my other xterms have sizes around 20MB and RSSs of around 3MB.

Thanks for any suggestions.
