groovebasin sometimes tries to shm_open and then everything dies #7

Open mrdomino opened 8 years ago

mrdomino commented 8 years ago

The sequence of steps that got me there:

  1. Try to make a backup of a large-ish (3GB or so) groovebasin grain.
  2. Sit there waiting for a while.
  3. Refresh the page, noting that the server appears down.

In the debug log was a message about trying to call shm_open and failing. The grain stayed like this across both an app restart and a sandstorm restart.

Were you eventually able to restart the grain?

I think the shm_open() error is not relevant to any crashes that you are observing. I see the error "shm_open() failed: Function not implemented" in the debug log at the beginning of each boot of the grain. I think it's failing because /dev/shm/ is not mounted, but it does appear to gracefully recover.

I restored from backup around then, so no,but I also didn't try very hard to restore it.
