MMS file handles not closed???



  • Hey guys, I'm looking for a bit of direction. I have a Nexus 5 on
    OTA 11
    Image 20191016-9670

    If I reboot my nexus 5 and I receive an MMS message 4 filehandles are open to the one MMS file:

    root@ubuntu-phablet:~# lsof 2>/dev/null | grep mms
    root@ubuntu-phablet:~# lsof 2>/dev/null | grep mms
    ubuntu-do 6059          phablet   10u      REG     179,28       493     696937 /home/phablet/.local/share/nuntium/store/2b74cc3336f35c253c9929ded3fc64e7.mms
    QDBusConn 6059 6060     phablet   10u      REG     179,28       493     696937 /home/phablet/.local/share/nuntium/store/2b74cc3336f35c253c9929ded3fc64e7.mms
    Qt\x20bea 6059 6061     phablet   10u      REG     179,28       493     696937 /home/phablet/.local/share/nuntium/store/2b74cc3336f35c253c9929ded3fc64e7.mms
    QNetworkA 6059 6068     phablet   10u      REG     179,28       493     696937 /home/phablet/.local/share/nuntium/store/2b74cc3336f35c253c9929ded3fc64e7.mms
    

    Then I send myself another MMS message it opens more and doesn't close the handle.

    Sending SMS messages does not affect this and they seem to be open forever. so I deleted one within the messages app and one from the command line:

    And this just keeps going up for each MMS file I receive. I found this because I run my own python script to bridge SMS/MMS messages to Matrix/Riot and so I never touch this device. Its plugged in all the time and I only ever use matrix on a different device to text. Eventually it fails because there is too many open files... It's worth noteing that the above testing was done before I started my python script and the below was after a couple months of uptime/use.

    This is how it looked before I rebooted my phone:

    Is this a problem for anyone else?

    I've never contributed to an open source project before and I'm pretty new to programming but I'd love to dig though the code myself. Anyone have any idea where I'd even start to look to find out where I'd need to close off these file handles? it seems like its in ubuntu-download-manager



  • I can't help, but I encourage you to keep digging. There is a running history of vague issues with mms on UT with no resolutions. There is probably something wrong that is not obvious, so you might be on to something.
