Hi Chip,

The db2fw threads are DB2 event monitor fast writer threads. Fast
writers are used for high volume, parallel writing of event monitor
data to table, file or pipe. The number of fast writer threads
started for a database is equal to the number of processors on the
system.

The Information Center is incorrectly stating these threads as event
monitor file writers. This documentation error will be corrected in a
future doc update.

Thanks,
Francis Wong
