Thanks for the quick reply, but... hmm. I'm gonna check this if and when
I reproduce the situation, but my machine would seem to have bucketloads
of space available:
$ df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/root        15G  3.8G   11G  27% /
devtmpfs        459M     0  459M   0% /dev
tmpfs           463M   76K  463M   1% /dev/shm
tmpfs           463M  6.3M  457M   2% /run
tmpfs           5.0M  4.0K  5.0M   1% /run/lock
tmpfs           463M     0  463M   0% /sys/fs/cgroup
/dev/mmcblk0p1   63M   21M   43M  33% /boot
tmpfs            93M     0   93M   0% /run/user/1000

Do you have any indication which filesystem/location JACK would be
looking for the condition? Could it also be a case of flag misuse?
