Otto,
A couple of machines here each with about 40 units attached
show authd using less than 100MB of memory, so that should
be a very safe high water mark for your 5 units. That would be
'-Xmx100M'.
Thanks, will try it, at the moment it is using 264Mb which while a lot
better still seems excessive.
Next biggest hog is xnewt at approx 1/2 Gb I hope removing some excess
fonts will help that.
Remember that utauthd is a system daemon and you
should only have one of them. That's in contrast
to Xnewt where you have one per user session.
There's a lot more to be gained by attacking the
user session. I understand some work is going on
with firefox to make it free pixmap memory for
non-visible tabs and recently-visited URLs more
aggressively. That would be an enormous help to X
server memory consumption. Also, X server memory
consumption can be deceptive. Alan C could say
more but IIRC large pixmaps allocate memory that,
while reused when no longer active, is never freed
by the X server. In other words, the X server
grabs memory and manages it for large pixmaps but
doesn't ever free it back to the system again. I
guess it could be paged out if truly unused. Do
be sure to look at RSS as well as total memory use
when identifying problematic processes.
