Public bug reported:
evolution-source-registry is using 100% CPU after login and never stops,
it continues to do so after kill/respawn or reboot. This started
sometime after upgrade to bionic and has been consistent for the last
couple of weeks.
Looking at the process with perf, it seems that it is looping calling
poll() via g_main_context_poll() via g_main_context_iterate in a hard
loop. In strace you can also see poll being called about 10,000
times/second.
poll([{fd=3, events=POLLIN}, {fd=11, events=POLLIN}], 2, 0) = 0
(Timeout)
gdb backtrace for the main thread reflected in the attached out.svg -
setting a breakpoint g_main_context_iterate is being called continually
but we never exit from g_main_loop_run.
