Ndo2db hanging after 2-3 weeks

[Alex Burger]

I am using Nagios 2.10 and ndoutils-1.4b6 with Nagvis.  Every 2-3 weeks 
Nagvis reports:

'NDO claims that Nagios did no status Update for more than "180" 
seconds.  Make sure that Nagios and ndo2db are running.'

If I attempt to stop Nagios, it will not stop properly:

# service nagios stop
Stopping nagios: ..........
Warning - nagios did not exit in a timely manner
# ps ax | grep nagios
18178 ?        Ss     0:00 /usr/local/nagios/bin/ndo2db -c 
/usr/local/nagios/etc/ndo2db.cfg
28978 ?        Ssl   40:55 /usr/local/nagios/bin/nagios -d 
/usr/local/nagios/etc/nagios.cfg
27550 ?        S      0:58 /usr/local/nagios/bin/ndo2db -c 
/usr/local/nagios/etc/ndo2db.cfg

If I kill the processes and restart nagios and ndo, Nagvis still does 
not work.  It doesn't appear to be a problem with Nagvis as ndo2db 
appears to hang.

What I have done to get around the problem is to drop the nagios 
database and re-create it using the ndo installdb script.  After that, 
everything works again for 2-3 weeks.  I have done this three times so 
far.  I have also seen this with Nagios 2.8 / ndoutils-1.4b6.  I am 
using RHEL4 64bit.

The nagios database was 287MB, and the previous time it was 273MB.

I have copies of the old databases so I can do some checks if needed.  I 
have included the output of mysqlshow --status nagios.

Would any of the fixes in ndoutils-1.4b7 help?  I will give it a try, 
but it will be 2-4 weeks before I can report back the results.
