[opennms-discuss] Capsd.log -> undeclared throwable exception

RHEL4
OpenNMS 1.3.9

I have what I think is a large number of these errors in my capsd.log  
file:

Undeclared throwable exception caught .....

Seems to be for FTP and SSH only.  I did some searching on the lists  
as well as good and didn't find a lot of info... Seems like it might  
be an OS level thing, too many files open, things like that, but I  
have no idea where to go.

Here's a few lines of the log file:

Hi David.
Well I've checked this now and it seems that it is all good.  Metrics 
were being collected just not displayed.  The metrics are now being 
displayed too.

Cheers,
John Natschev

[opennms-discuss] Upgrading OpenNMS from 1.3.7 to 1.3.9 on Solairs 10

	
I'm looking to upgrade Opennms from 1.3.7 to 1.3.9 on a Soalris 10  
box. The original install was with a Solaris package, but the  
sourceforge site only has rpm's. Also do I need to install 1.3.8  
first ??

Thanks in advance,

Eric

Re: [opennms-discuss] Capsd.log -> undeclared throwable exception

fyi,

This appears to be preventing OpenNMS from discovering the FTP service  
on several nodes, as well as SSH (though I don't care about this as  
much as ftp).

Not sure if that helps any, but it is what it is.

Re: [opennms-discuss] Capsd.log -> undeclared throwable exception

Yo Buzz,

I think this is more likely a configuration issue on the SSH and FTP  
servers.  Are you by any chance using TCP Wrappers on those hosts?

As an experiment, what happens if you telnet from the OpenNMS server  
to port 22 (SSH) and to port 21 (FTP) on one of the problem hosts?   
Under normal circumstances, you should see something like this for SSH:

$ telnet vishnu 22
Trying x.x.x.x...
Connected to vishnu.
Escape character is '^]'.
SSH-2.0-OpenSSH_4.3p2 Debian-8ubuntu1

Same thing for FTP on port 21, except the banner will say something  
like "220 (vsFTPd 2.0.5)" instead of the "SSH-2.0-OpenSSH..." above.

[opennms-discuss] OpenNMS crashes...

...well, more accurately, the Java VM surrounding OpenNMS does - see
attached error log.

Unfortunately I have next to no idea why this happens - and it happens
in a completely unpredictable way, with no apparent connection between
events. Sometimes it'll run for days or even weeks, and sometimes it'll
die on two consecutive days or more than once on a given day (twice
today).

output.log looks perfectly normal every time, but traps the JVM error
before closing down. Other than that entry, the JVM log is all I've got.

The system is:

Version: 1.3.10-SNAPSHOT
Server Time: Thu Jan 03 14:08:21 GMT 2008
Client Time: Thu Jan 03 2008 14:08:21 GMT+0000 (BST)
Java Version: 1.5.0_13 Sun Microsystems Inc.
Java Virtual Machine: 1.5.0_13-b05 Sun Microsystems Inc.
Operating System: Linux 2.6.23.1-42.fc8 (i386)
Servlet Container: jetty-6.1.5 (Servlet Spec 2.5)

This is opennms-core-1.3.10-0.8094.snapshot, but this has happened with
several other previous versions too. It's very likely a local (ie. not
OpenNMS) problem, but I'm damned if I can work it out.

If anyone can help, that'd be great - if you need more info, just ask.

Thanks

Graeme

I suspect you're right, JVM crashes are rare and usually point to a  
problem with the system where the JVM is running.

I'd suggest grabbing and installing a Java 6 JDK and configuring  
OpenNMS to use that in place of the Java 5 one you have in place now.   
Just run:

/opt/opennms/bin/runjava -s /path/to/java6sdk/bin/java

And then restart OpenNMS.  There's certainly no guarantee that this  
will fix your problem, but even if it does not, you've at least  
eliminated one variable.

Looking at your patch, I see that you did not change the alias names  
of the mibObjs in datacollection-config.xml.  Did you blow away the  
old RRD / JRB files after making this change?  If you did not, then  
the values are still being treated as gauges, since the treatment of a  
given DS is set at the time of RRD creation and cannot be subsequently  
changed.

We would not commit your patch as it stands now because it would cause  
the same problem you've observed on every system where these mibObjs  
have been previously collected.  You would need to change the alias  
names of the new mibObjs and update the netsnmp.interrupts and  
netsnmp.context reports or in snmp-graph.properties to do this the  
right way.
