Explanation:  The condition that issues this message is no cause for alarm, and it only applies to 16-bit host adapters because of their 16 MB addressing limitation. The message indicates that the server cannot allocate any new memory buffers below 16 MB for I/O use. All I/O channels are still valid, but I/O performance will decrease because the server must wait for existing buffers to recycle.

Action:  If the maximum has not already been specified, increase the value of the Reserved Buffers Below 16 Meg parameter in the startup.ncf file.
