[Bug 1344869] Re: simple-scan consumes 100% cpu and fills disk with logs attempting to scan wirelessly with Brother MFC-7860DW
Yes, I confirm that the issue is resolved with 3.13.4.2-0ubuntu1. Not relevant to this bug, but I do notice that the scan speed is quit slow using simple-scan. Comparing with xsane at the same resolution (300dpi): - xsane: 23 seconds - simple-scan: 2 minutes. Thanks very much for the fast turn-around! ** Changed in: simple-scan (Ubuntu) Status: Incomplete = Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1344869 Title: simple-scan consumes 100% cpu and fills disk with logs attempting to scan wirelessly with Brother MFC-7860DW To manage notifications about this bug go to: https://bugs.launchpad.net/simple-scan/+bug/1344869/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1344869] Re: simple-scan consumes 100% cpu and fills disk with logs attempting to scan wirelessly with Brother MFC-7860DW
Hi Robert, Sorry to be vague, but I don't actually scan much so the last time I recall doing it I was running trusty. Yes, the proprietary brother drivers are required for wireless scanning AIUI. $ dpkg -l | grep brscan ii brscan-skey 0.2.4-1 amd64Brother Linux scanner S-KEY tool ii brscan4 0.4.2-3 amd64Brother Scanner Driver Gah - I've just got an updated simple-scan package (3.13.4-0ubuntu1). The behaviour with this version is different; simple-scan tellms me there is no scanner connected, yet if I click scan, it clearly is talking to the scanner (which I can hear whirring in the background). So, although I no longer get ENOSPC, the scanned image never appears in simple-scan. When I quit simple-scan, it seems a command is sent to the scanner to reset since it sounds like it is resetting itself. Updated simple-scan debug log attached. ** Attachment added: 'simple-scan --debug' log https://bugs.launchpad.net/ubuntu/+source/simple-scan/+bug/1344869/+attachment/4158766/+files/simple-scan-21july2014.log.gz -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1344869 Title: simple-scan consumes 100% cpu and fills disk with logs attempting to scan wirelessly with Brother MFC-7860DW To manage notifications about this bug go to: https://bugs.launchpad.net/simple-scan/+bug/1344869/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I think this is fixed in simple-scan 3.13.4.2, please re-test. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1344869 Title: simple-scan consumes 100% cpu and fills disk with logs attempting to scan wirelessly with Brother MFC-7860DW To manage notifications about this bug go to: https://bugs.launchpad.net/simple-scan/+bug/1344869/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

When did this used to work? I'm assuming you have the Brother proprietary drivers installed, can you check the versions of the 'brscan', 'brscan2', 'brscan3' and 'brscan4' packages? Can you get a log containing the calls leading up to the loop (the attached log is from a fresh start where no scanning was started). You can get the log from simple-scan with: $ simple-scan --debug if that is easier to capture it. You can also get the equivalent from xsane by running: $ ltrace -l libsane.so.1 xsane The particular response from the driver is in fact valid, we are correctly waiting for SANE_STATUS_EOF before stopping the sane_reads. So this might be a buggy driver that's triggered by the options that simple-scan sets. ** Changed in: simple-scan (Ubuntu) Status: New = Incomplete ** Changed in: simple-scan (Ubuntu) Importance: Undecided = Medium ** Also affects: simple-scan Importance: Undecided Status: New ** Changed in: simple-scan Status: New = Incomplete ** Changed in: simple-scan Importance: Undecided = Medium -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1344869 Title: simple-scan consumes 100% cpu and fills disk with logs attempting to scan wirelessly with Brother MFC-7860DW To manage notifications about this bug go to: https://bugs.launchpad.net/simple-scan/+bug/1344869/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
