id summary reporter owner description type status component version resolution keywords cc guest host 3498 Possible memory leak during paused VM Pete "I'm running the non-OSE version of VirtualBox 2.1.4. The VM guest is running WinXP Pro. If I boot the machine and then pause the guest, my system memory usage starts to increase. After a few hours all ram gets used up. Immediately upon unpausing the VM, the ram is released. Below is a sequence of `free' commands from just before pausing, just before unpausing, immediately after unpausing, and then a few minutes later. {{{ foo@bar:~$ date && free Wed Mar 4 21:03:32 MST 2009 total used free shared buffers cached Mem: 4054092 3018400 1035692 0 37476 1400648 -/+ buffers/cache: 1580276 2473816 Swap: 1951856 2208 1949648 foo@bar:~$ date && free Wed Mar 4 21:16:20 MST 2009 total used free shared buffers cached Mem: 4054092 3666676 387416 0 38628 1481980 -/+ buffers/cache: 2146068 1908024 Swap: 1951856 2208 1949648 foo@bar:~$ date && free Wed Mar 4 21:16:27 MST 2009 total used free shared buffers cached Mem: 4054092 3117800 936292 0 38640 1482028 -/+ buffers/cache: 1597132 2456960 Swap: 1951856 2208 1949648 foo@bar:~$ date && free Wed Mar 4 21:21:13 MST 2009 total used free shared buffers cached Mem: 4054092 3013084 1041008 0 39100 1377408 -/+ buffers/cache: 1596576 2457516 Swap: 1951856 2208 1949648 }}} This is a major problem for me. I really like to have the VM open, as I use it to VPN, but I want to be able to pause because I run large optimizations too. " defect closed other VirtualBox 2.1.4 fixed Windows other
