Experience a similar error when testing my app recorder. I am trying to add a "share" ability via the content-hub. I get to the point when the peer picker window is displayed after which there is a failed event.
On checking my app logs I find: libust[24601/24606]: Error: Error opening shm /lttng-ust-wait-5-32011 (in get_wait_shm() at lttng-ust-comm.c:958) libust[18402/18405]: Error: Error opening shm /lttng-ust-wait-5 (in get_wait_shm() at lttng-ust-comm.c:958) libust[18402/18405]: Error: Error opening shm /lttng-ust-wait-5 (in get_wait_shm() at lttng-ust-comm.c:958) libust[18402/18406]: Error: Error opening shm /lttng-ust-wait-5-32011 (in get_wait_shm() at lttng-ust-comm.c:958) libust[18402/18406]: Error: Error opening shm /lttng-ust-wait-5-32011 (in get_wait_shm() at lttng-ust-comm.c:958) libust[20659/20663]: Error: Error opening shm /lttng-ust-wait-5-32011 (in get_wait_shm() at lttng-ust-comm.c:958) libust[20659/20663]: Error: Error opening shm /lttng-ust-wait-5-32011 (in get_wait_shm() at lttng-ust-comm.c:958) libust[20659/20662]: Error: Error opening shm /lttng-ust-wait-5 (in get_wait_shm() at lttng-ust-comm.c:958) libust[20659/20662]: Error: Error opening shm /lttng-ust-wait-5 (in get_wait_shm() at lttng-ust-comm.c:958) libust[9690/9694]: Error: Error opening shm /lttng-ust-wait-5-32011 (in get_wait_shm() at lttng-ust-comm.c:958) libust[9690/9694]: Error: Error opening shm /lttng-ust-wait-5-32011 (in get_wait_shm() at lttng-ust-comm.c:958) libust[9690/9693]: Error: Error opening shm /lttng-ust-wait-5 (in get_wait_shm() at lttng-ust-comm.c:958) libust[9690/9693]: Error: Error opening shm /lttng-ust-wait-5 (in get_wait_shm() at lttng-ust-comm.c:958) libust[14795/14798]: Error: Error opening shm /lttng-ust-wait-5 (in get_wait_shm() at lttng-ust-comm.c:958) libust[14795/14798]: Error: Error opening shm /lttng-ust-wait-5 (in get_wait_shm() at lttng-ust-comm.c:958) libust[14795/14799]: Error: Error opening shm /lttng-ust-wait-5-32011 (in get_wait_shm() at lttng-ust-comm.c:958) libust[14795/14799]: Error: Error opening shm /lttng-ust-wait-5-32011 (in get_wait_shm() at lttng-ust-comm.c:958) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to content-hub in Ubuntu. https://bugs.launchpad.net/bugs/1404302 Title: liblttng-ust0 Error opening shm /lttng-ust-wait-5 Status in Client Developer Experience: Confirmed Status in platform-api: New Status in content-hub package in Ubuntu: New Status in qtmir package in Ubuntu: Invalid Status in webbrowser-app package in Ubuntu: Confirmed Bug description: Confined apps don't have access to this and continuously produce this error message in stderr: libust[31283/31285]: Error: Error opening shm /lttng-ust-wait-5 (in get_wait_shm() at lttng-ust-comm.c:958) This is printed to the application's log about once every other second and makes it hard to read the application's own debug output.
