since upgrading to 5.02 RHEL_64ne, the system swap use is ~70% and the load quite high, this reaches ~ 100% when we run netbackup at 6am on /opt/zimbra/backup.
The server is quite beefy 4G RAM, 2G Xeon processor, 1T disk space.
The system has ~ 4000 active users any suggestion on how to improve the system,
or does it still require extra ram.
thanks for any replies
