I was curious if anyone had any experience with running VERITAS NetBackup (specifically 6.5.4) for Linux on System z (SLES10)? We've noticed extremely high amounts of memory usage when VERITAS is running a full back up of a server; end result is swapping to disk.
Scenario prior to full back up: Server has approximately 1gb of free virtual memory Server has 256mb of primary swap, not being used (VDISK) Server has 512mb of secondary swap, not being used (VDISK) NetBackup starts: VERITAS ties up the 1 GB of free virtual memory, then the 256 MB of primary VDISK is used, spilling over and using up the 512 MB of secondary VDISK, and ends up swapping to disk. This process will last approximately 1-2 hours while it backs up approximately 100 GB of data. Netback is also running in multiplex mode during the full back ups. Another note, the incremental back ups are running in non-multiplex mode and we don't experience the same type of memory usage. The caveat being, obviously the incremental back ups are not backing up as much data. We are not seeing the same type of memory issues on the x86, VMware, etc. This issue seems to be isolated to the s390x environment? I was curious if anyone has run into this issue before?
