swap_pager on cloud server

[David Mehler]

Hello,

I've got a FreeBSd 10.3 vps. Today it started giving me:

swap_pager: indefinite wait buffer: bufobj: 0, blkno: 249488, size: 16384

When it does this my ssh session becomes unresponsive. The vps service
offers out of ban services so that I can have an ssh serial console
access. This issue even locks up the console. The only solution is a
reboot.

I've read that the issue is one of paging and swap not being able to
be written to disk.

The disks are all virtual I do not believe these disks can go bad so
I'm assuming it's software or system configuration.

I'd appreciate any suggestions.

Thanks.
Dave.
