Note that to OTA-7 we fixed one stale process lock files bug #1500444. That was the 2015-05-26 commit from http://code.qt.io/cgit/qt/qtbase.git/log/src/corelib/io/qlockfile_unix.cpp
The only other patch that could sound worthwhile would be the syncing- to-disk commit http://code.qt.io/cgit/qt/qtbase.git/commit/src/corelib/io/qlockfile_unix.cpp?id=4accd865c24b7ed918cb705913478bab5aeb5e6e , and it does state "to avoid leaving an empty lock file on crash".. maybe on kill too? https://bugreports.qt.io/browse/QTBUG-44771 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1576989 Title: stale lock files freeze apps To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1576989/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
