A new release of NDOUtils (1.5.2) is now available from SourceForge.
NDOUtils uses a message queue to communicate between the module that is loaded into Nagios Core and the daemon used to write data to the database. In this version, if there are too few resources available in the queue to send a message, the module will retry sending the message up to 20 times. It will also log a warning if the system resources are low enough to require retries. Finally, the README has been updated with instructions for tuning the message parameters in the Linux kernel to increase the message queue resources.
