I thought I had already read all that the STAX UG said about this, but apparently not. It looks like when a timer pops it's supposed to kill any processes it envelops ...
So perhaps the problem I am having is the nature of the "error." The
process actually does not exist on the machine anymore, but STAF/STAX is
still waiting for it.

Subject: [staf-users] hung processes and timers
We use STAF/STAX for testing, so this particular problem is in a STAX test
"server" -> STAF "client" situation.
Occasionally, I get a hung process... what seems to happen is that the
command returns, but for whatever reason, the STAX machine doesn't get the
return. Normally, this wouldn't be too difficult; just put a timer on the
process (for example, we install our product on AIX using installp and it
shouldn't take more than a minute or two at most).
However, it seems that timers do not ... interrupt, I guess, a process?
Quick code example (on-the-fly, not copy/paste from actual XML):
<timer duration="'1m'">
<sequence>
<process name="'cat /etc/filesystems'">
<location>machineIP</location>
<command mode="'shell'">"cat /etc/filesystems"</command>
<stderr mode="'stdout'" />
<returnstdout />
</process>
<log level="'trace'">"Got /etc/filesystems:\n%s" % STAXResult[0][1]</log>
</sequence>
</timer>
<if expr="RC != 0">
<log level="'error'">"ERROR: trying to cat /etc/filesystems took longer
than 1m!"</log>
</if>
I guess my question is: is it true that a timer cannot interrupt a "hung"
process and force STAX to move on, or am I doing something wrong :)
And if it is true, is that even possible, or should I not open a feature
request.
Thanks!
