Windows server 2008 memory leak
Posted on 2008-10-09
I have a system in place disk based backups ofseveral computer to a file server using NTBackup and scheduled tasks. It's been working fine for several years now. I replaced the file server with a new server running windows 2008. I have NTbackup running the backup and then verifying it. The backup runs fine but as soon as the verify starts the 2008 syserve starts using all the systems memory. I set up a test backup of about 6 gigabytes and monitored memory usage on the 2008 server using task manager. As soon as the verify starts the memory usage climb from about 1 GB to 7 GB (I have 12 GB in the system) then as soon as ithe virify finishes it drops back to 1 GB. It looks like 2008 is writing the whole backup file to system memory.
I have tried this on two seperate 2008 system and they both did the same thing. I also went back and checked it on the 2003 server and there was no increase in memory usage.
