Description

Hello,

I'm running DFly on a VPS, and sometimes it crashes but failed to dump, showing such an error:

Dump failed. Partition too small.

Today I tested the crash dump on a VirtualBox machine with DFly-5.0.0 LiveCD. The virtual machine has 512 MB RAM, and configured with a 1 GB swap partition as the dump device. Then I manually broke into debugger "db>", type "call dumpsys", but it failed with code 0x23 and message "Dump failed. Partition too small." See also the attached screenshot 1.

As a comparison, I booted FreeBSD 11.1 LiveCD on the same virtual machine, set dump device, manually triggered the panic with "sysctl debug.kdb.panic=1". It dumped successfully and rebooted, then I saved the dump information. The attached screenshot 2 shows the information.

I also have a bare metal running DFly, and I can provide further tests if necessary.

Cheers,
Aly
