Hi I have set of Citrix Metaframe FR3 (Production) servers which are installed with Veritas Net backup 5.1 Client to take the Network backup. An d I have McAfee antivirus enterprise edition installed on all of these servers. Rest of these we have Landesk Client also there in the same servers. Then problem is I have enough space in the C: and D: drive nearly 2 GB each. Still I am getting the error of "C: Drive almost out of space " error ! Then we investigated on this issue and found out that while Netbackup (Veritas) tries to take the backup it creates a tmp file (_vxfiVspCacheFile_0.tmp) and automatically it should remove the same after the backup by Veritas Netbackup client itself. The problem was McAfee protects this files , deleting from the drive which will be having almost a size of 1 to 2 GB .But in Mcafee Enterprise console we have the Low risk and high risk process where we can specify the SSM.exe (Program which is involved in the Backup Process) , I added the SSM.exe in low risk processes still every day I am getting the C: almost out of space through the Event viewer and LANDesk Client . So I think the issue is related to some other thing. Any body can please help me in this.. _________ Nagarajan Haridas Symphony Citrix Operational Support: Team Member SLK Software Services: Bangalore: India Office: 91-80-23515721 Ext: 207
