During normal processing, additional buffer pool space is required beyond that specified in the BUFPOOLSIZE in the server options file. The additional kilobytes of buffer pool space that are required are indicated in the message.
Server operation continues; the additional buffer pool space is obtained from available server memory.
If the current server load is typical, consider increasing the size specified for your BUFPOOLSIZE option by the number of kilobytes specified in the message. To do this, you must halt the server, change the options file, and then restart the server.
