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.
