Stefan,

I don't know if this is your problem.  I just suggested it as a
possibility for you to consider.  I originally saw random lockups on a
BB system after upgrading from Redhat 7 to (8 or 9, I don't remember).
I thought this might be possible on other versions or distributions as
well.   
The solution in my case was to either:  
1) Down-grade the compiler to match the OS .
2) Recompile the kernel.
3) Change OS versions (sounds like you may have tried this).

I hope this helps in some way.  Good luck on your problem.

Jeff

Hello Jeffery,

do you think we see this issue because the kernel was built with a
different compiler than I was using for building the hobbit server?

@Henrik - do you think this could be the problem?

Regards,
Stefan

on a BB system where<br>&gt;the kernel was compiled with a different
version compiler than was<br>&gt;included with the system and there were some IPC-related changes in<br>&gt;compiler versions.<br>&gt;<br>&gt;-----Original Message-----<br>&gt;From: Stefan

Unavailable - again<br>&gt;<br>&gt;Hi Henrik,<br>&gt;<br>&gt;we have several
own-written scripts (mostly in perl) which monitor<br>&gt;oracle<br>&gt;instances,
bea weblogic servers. There is one for hardware monitoring -<br>&gt;HP<br>&gt;(Intel) and Sun Servers (prtdiag based) and some are
just the output of<br>&gt;a<br>&gt;http request to the software running on
that weblogic servers.<br>&gt;I have just one server for testing, it's a HP
DL 360. We are running<br>&gt;Redhat<br>&gt;Enterprise Server 3 but I've
tried it with a SuSE 9.3 too.<br>&gt;<br>&gt;Regards,<br>&gt;<br>&gt;Stefan<br>&gt;<br>&gt;&lt;br

&amp;gt; It would be great if<br>&gt;you<br>&gt;can put me in cc. If you want I can
try to assist&lt;br&gt;&amp;gt; &amp;gt; you. I'm<br>&gt;at a<br>&gt;point
where I don't know what to try anymore. I think it&lt;br&gt;&amp;gt; &amp;gt;<br>&gt;isn't<br>&gt;easy for Henrik to find this issue - I have
no coredumps and<br>&gt;nothing&lt;br&gt;&amp;gt;<br>&gt;&amp;gt; in the logfile what could help.&lt;br&gt;&amp;gt;&lt;br&gt;&amp;gt;Yes, this is

a<br>&gt;really<br>&gt;nasty problem. Vernon and I though we had it&lt;br&gt;&amp;gt;nailed down by the<br>&gt;end<br>&gt;of last week,
but there's more to it than&lt;br&gt;&amp;gt;what we found<br>&gt;then.&lt;br&gt;&amp;gt;&lt;br&gt;&amp;gt;What kind of
external scripts run on your clients,<br>&gt;apart from the BB&lt;br&gt;&amp;gt;client ? The current suspicion is that this is<br>&gt;triggered by a status&lt;br&gt;&amp;gt;message that is handled

badly by Hobbit<br>&gt;causing<br>&gt;this lock-up. So I'm&lt;br&gt;&amp;gt;trying to see if there might be something in<br>&gt;<br>&gt;common between your setups.&lt;br&gt;&amp;gt;&lt;br&gt;&amp;gt;And what kind of system are<br>&gt;you<br>&gt;running Hobbit on ? If Linux, which&lt;br&gt;&amp;gt;distribution ? Another<br>&gt;suspicion<br>&gt;I
have is that this might be a&lt;br&gt;&amp;gt;problem with the implementation

of<br>&gt;<br>&gt;SysV IPC<br>&gt;semaphores.&lt;br&gt;&amp;gt;&lt;br&gt;&amp;gt;&lt;br&gt;&amp
