Threads blocked on SYSTM

[Sanjaya_1]

Hi
I have running my application on Itanium Server that to on HPUX 11i.
Most of my application threads are blocked on SYSTM, i donot know what it means.
I believe threads are waiting for some resouce(what kind of resource is this) , could you guys through some light on this.
basically i am not able to scale my application but CPU Utilization is < 20 %

Hi Sanjaya

Can u brief about the applications you are using. and also post the output of top command

[Kent Ostby]

Here is the basic definition of SYSTM:

Waiting for access to a
system resource or lock.
These resources include data
structures from the LVM,
VFS, UFS, JFS, and Disk
Quota subsystems. "SYSTM"
is the "catch-all" wait
state for blocks on system
resources that are not
common enough or long enough
to warrant their own stop
state.

What version are you on ? 11.11, 11.22, 11.23 ?

What does tusc show ?

Hi

Do you have DCE installed?

We are running into the same issue on a RP7400 running HP-UX 11.00.

The Java threads on WebMethods basically hang after a while. When I look at them they are primarily in SYSTM wait state. HP is taking a look at this as there is at least one other customer with this same WebMethods/Java1.4 hang issue.
