I am also seeing a memory run off with the Veeam Data Collection service. This is on a stand alone server (no virtualization) with 12 GB of memory. I have to restart the sever prior to the backup run. The service with take all available memory over the course of a few days. I restarted the server on Friday and by Sunday it has consumed 7GB of memory. The server will be maxed out on memory by the end of the day Monday. We recently upgraded to Veeam 9.0 when we noticed the issue, but I believe this has been happening for several months. Also to note, when the service has the memory maxed out, it fails doing the backups to tape. By this thread, it seems there are several people having this issue. So I do not believe this is a one on one issue with the software and hope to see a patch VERY soon for this issue. Any suggestions on a solution to this issue would be greatly appreciated.
