I run pulseaudio for days on end. It drives a house sound system, which
plays music and radio to a cron schedule, even when I am away. I have a
USB sound card and an internal pci sound device both driven via a
combined sink.
Every few days or so, the pulseaudio server dies with the one of
following messages. Logging out-in restores the service. The problem is
that I'd like to have it last at least 2-3 weeks.
localhost pulseaudio[25023]: memblock.c: Assertion
'pa_atomic_load(&b->pool->stat.n_imported) > 0' failed at
pulsecore/memblock.c:634, function memblock_replace_import(). Aborting.
localhost pulseaudio[19753]: memblock.c: Assertion
'pa_atomic_load(&b->pool->stat.n_imported) > 0' failed at
pulsecore/memblock.c:188, function stat_remove(). Aborting.
I have only recently joined the mailing list and I have not seen any
threads that deal with this particular problem. Any advice appreciated.
Here are my my machine environment:
