Martin Birgmeier <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- Summary|dd: stdout: Cannot allocate |virtualbox/memory allocator |memory |problem: "dd: stdout: | |Cannot allocate memory" Version|10.1-RELEASE |10.2-RELEASE --- Comment #1 from Martin Birgmeier <[email protected]> --- In 10.2, the same behavior still persists. The symptom is that when VirtualBox is running, a dd from a disk partition does not run to completion, but aborts with the error messsage "dd: cannot allocate memory". So, the scenario is: - I want to low-level copy a disk partition using dd - At the same time, a VirtualBox instance is running Expected result: - dd runs to completion - VirtualBox does not affect dd Actual result: - As long as VirtualBox is running, dd aborts after a random number of blocks read Workaround: - Do not start VirtualBox while dd is running Is this some interaction in how the kernel allocates buffers? It surely isn't really a userspace problem? -- Martin -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
