When simple-scan is spinning, the following entry is added to the log
repeatedly until ENOSPC:
[+15,29s] DEBUG: scanner.vala:1310: sane_read (0) -> (SANE_STATUS_GOOD,
0)
Further details:
$ cat /proc/$(pidof simple-scan)/stack

Title:
simple-scan consumes 100% cpu and fills disk with logs attempting to
scan wirelessly with Brother MFC-7860DW
Status in “simple-scan” package in Ubuntu:
New
Bug description:
Attempting to scan via wifi from a Brother MFC-7860 DW fails; the
scanner shows scanning but:
- no image appears in simple-scan.
- simple-scan consumes 100% CPU
- the ~/.cache/simple-scan/simple-scan.log grows indefinately until disk
space is exhausted.
This used to work perfectly and indeed the following provides an
instant work-around:
$ sudo apt-get install -y xsane && xsane
