Action: Increase the value of the pageCachesize parameter:
Unload the NFS Gateway by executing gystop.
Reload nfsgy with a larger pageCacheSize. To do this, modify gystart.ncf (or anywhere nfsgy is being loaded, including directly at the console prompt). After modifying the NCF file, execute it to reload nfsgy.nlm.
For more details, refer to the pageCachesize parameter description in Setting NFS Gateway Parameters .
Action: If increasing the pageCachesize does not have any impact, try increasing the value of the CacheSize parameter in sys:\system\bti.cfg. Refer to the guidelines mentioned in Configuring NFS Gateway for the First Time .
