I've now made devmon's --debug mode continue to send status messages to the 
BB/Hobbit server, so it is now possible to run devmon in debug mode (e.g. 
under screen or similar), until it hits the problem. The last few lines of 
output when devmon stops reporting may be useful.

We're still only seeing this about once a week (on RHEL4 - no occurrences in 
127 days on RHEL5), so if others are seeing it more often, please try this 
patch, and then run devmon in a screen session with '-vvvvv --debug'

http://devmon.svn.sourceforge.net/viewvc/devmon/trunk/modules/dm_msg.pm?view=patch&r1=93&r2=92&pathrev=93

I would like to try and get a beta release of 0.3.1 out this week if possible, 
with or without fixing the root cause (to at least enable more people to try 
and find the problem), although I would much prefer trying to fix it if 
possible.

I've been running with this patch on the two affected RHEL4 boxes, and I have 
noticed that devmon was killed at some stage by a logrotate script that was 
calling '/etc/init.d/devmon restart'. On the box running RHEL5, it was calling 
'/etc/init.d/devmon condrestart' which is not a possible argument (explaining 
why it was not affected, if this was indeed the problem).

In the meantime, I've made devmon close and re-open the log file on HUP, so 
log rotation should work better without having to try and restart devmon. I'm 
also improving the init script (for Red-Hat style systems) to stop devmon more 
reliably (in the case where the pid file is not in /var/run, but a sub-
directory, which is necessary in the case where devmon is running as non-
root).

Effectively, I think this is a bug affecting anyone using my devmon packages 
for Mandriva or RHEL/Centos ... which should be fixed soon.

I am not sure if this lograte script is responsible for all the purpleness on 
the two RHEL4 boxes I was testing on, so I will continue testing for a few 
days while I look at the last few issues for 0.3.1.

However, if anyone who is affected a lot by this issue can check whether this 
might be an explanation for their problems, that would be great.

log rotation might be an additional issue. However we are running devmon
on several Debian based systems and I haven't configured log rotation
yet. However the purple issue occured, too.

Let's see if running in debug mode gives a hint on the reason. Up to now
it is running fine in debug mode.

Running this for a few days turned this up, one second (but about 100 lines) 
before devmon stopped doing anything:

[09-01-07@22:45:12] DEBUG SNMP: Pooling 1 oids
Can't use an undefined value as a HASH reference
at /usr/share/devmon/modules/dm_snmp.pm line 399, <$__ANONIO__> line
59375.
[09-01-07@22:45:12] DEBUG SNMP: Failed queries 0



I have changed some of the logging inside the affected subroutine (to print 
the fork number ($form_num) for every "DEBUG SNMP"  line) to try and confirm 
what I think is happening. I will also try and see if I can test a fix 
(without devmon itself).

But, again, confirmation from others would help ...

one of our devmon servers turned purple this morning. It stopped here:

[09-01-09@07:24:36] DEBUG TEMPLATES: running post_template_load()
[09-01-09@07:24:36] DEBUG CFG: running read_hosts
[09-01-09@07:24:36] DEBUG SNMP: running poll_devices()
[09-01-09@07:24:36] Starting snmp queries
[09-01-09@07:24:36] Getting device status from hobbit at xx.xx.xx.xx:1984

It is possible, that this system couldn't reach the hobbit server
at that time. However it didn't recover from this status.

The debug log shows some messages like 'Use of uninitialized value in addition
(+) at (eval 94189069) line 1, <$__ANONIO__> line 1450529.', too. But they are
shown in every cycle and not just before devmon stopped.

Hmm, try as I might I can't get hobbitd to die between  "my $sock = 
IO::Socket::INET->new" (or "if(defined $sock)" ) and while(<$sock>).

However, simply adding a timeout to the socket may be enough to fix this, can 
you try with this patch ?

Yes, I think these may depend on the templates, and are non-fatal, but I may 
consider trying to clean them up (to reduce noise in the log or avoid eating 
up space in the scrollback buffer in screen) for situations like this.

I've added this patch to our devmon servers. Let's see what happens.

yes, I've applied it to a couple of servers. All of them - still running in
debug mode - didn't turn purple until now.

So this might have been the solution to the problem.

[Geoff H. <geo...@gm...>]

Once the patch is finalized, is there going to be a message sent out to
everyone? Mine is going devmon is going purple now 1 to 2 times per day on
average.

Re: [Devmon] Solution for the purple issue?

Well, one definite potential cause is addressed, and I have released 0.3.1-
beta1 with the fix to that. If it doesn't fix things for you, then you should 
run 0.3.1-beta1 under screen in debug mode, and if it hangs (goes purple), 
send all the output you have available in the screen session. You can also 
have screen record to file, but it's a *lot* of output.


There are a number of other bug fixes in 0.3.1-beta1, and a few new features, 
and I doubt there are any new problems, so it is worthwhile trying.

We've seen a different cause here, which isn't fixed in 0.3.1-beta1, but it 
took 40 days running in debug mode to reproduce it on a smallish installation 
(and about 2 weeks on one a bit bigger).

I'm testing a fix for that one, but it's going to take a bit longer to see if 
it is fixed.

if possible try to apply the timeout patch.

Our devmon servers also turned purple nearly every day until I've set up
a cronjob to restart three times per hour. However since running in
debug mode it happened only once. Which was possibly caused by the
missing timeout. Since applying this patch everything runs fine.

However I don't know what happens when disabling debug mode again.

Best regards
Thomas

Okay thanks I will try that. Does this increase the logfile size created by
devmon, as it is debug all the time? Is that the only change?

by the way, I've disabled debug mode for quite a couple of days and
it didn't turn purple up to now :-)
