It seems to me ndo problems are often related to mysql performance...
On my smallish nagios test instance (50 hosts - 300 services), the
db weighs ~300 Mb / 1M records, and everything works fine since
I switched to innodb storage engine. Don't know whether it's really
related (table locking vs. record locking)...
I think ndo is able to cause a good deal of stress to any "untuned"
mysql server, the README could be updated to include a couple
of tuning tips (innodb pool sizing, small query cache as most
requests seem to contain variable arguments, pre-allocating
innodb storage, etc..). If a mysql wizard reads this, please give
your advice :)

have a nice day
