The whining about /usr/lib/X11/fonts/misc is normal, in my experience, and not a problem. However, those AUDIT messages I've never seen before. Do you perhaps have a firewall or other security-related policy causing problems?

No, The SunRays have their own network segment, iptables has no rules on the sunray-server, selinux is set to permissive. So that would be a no.

Do you see anything helpful in the GDM log files: /var/log/gdm?

There's 215 files there!

Some are empty and some of them print out various messages:

------

Now the weird thing is that /usr/lib/X11/fonts/misc dir, it isn't there in RHEL5, there's a package called xorg-x11-fonts-misc.noarch but it is already installed!

Other than that I don't get much clue out of this.

I have RHEL 5 and SRSS 4.2 EA2 (no option of updating right now)

Last system we used was RHEL 4 AS + SRSS 4.1

It worked as usual (everything is fine, USB doesn't work)
But we had to move to RHEL 5 because RHEL 4 was just to old.

Since then we've experienced performance problems. Load is often high (leading to stuttering sound in audio), programs takes time to start, authentication can take 5-10s instead of 0.5s, login can be slow and sometimes smartcard doesn't work.

top shows that cpu is mostly idle (so it isn't a program hogging cpu)
top shows lots of free ram, and no swap used
network traffic is low and sound stutters occurs also when files are played from local filesystem - so it isn't our NFS

vmstat shows r going between 1 and 20
vmstat shows b at a constant 1

syslog spews out loads of these:

Feb 16 11:20:12 sunray0 utxsun:
Feb 16 11:20:12 sunray0 utxsun: Can not determine token ID
Feb 16 11:20:12 sunray0 gdm-XKeepsCrashing: GDM can't start X server.
Feb 16 11:20:13 sunray0 utxconfig: Error: could not open file '/var/opt/SUNWut/displays/21' for reading. Feb 16 11:20:13 sunray0 utxsun: Error: could not open file '/var/opt/SUNWut/displays/21' for reading.
Feb 16 11:20:13 sunray0 utxsun:
Feb 16 11:20:13 sunray0 utxsun: Can not determine token ID

and if i shut of syslogd vmstat show b = 0 and load goes down a bit.

There's also LOADS of processes called gdm-binary. They last a couple of seconds, then respawn with a new PID, so I can't renice them. On a machine with 10 logged in users, there can be 30-80 gdm-binary processes. They pop up in top, taking 15% each like once every couple of seconds.

This is becoming unbearable so I'd like some help on this.

I suspect there is something wrong, something that keeps respawning that doesn't need to. I have the same problem on both my SunRay servers.

I would be grateful for any eventual help.
