Do the gem_caching clients disappear if you wait long enough? While the clients are still there, does 'strace -p <gem_caching_pid>' show any output? According to the log, the gem_caching is showing in the client list too early. Perhaps ordering/race issue in the testrunner. Similar symptomps as in https://bugs.freedesktop.org/show_bug.cgi?id=85831 *** Bug 85831 has been marked as a duplicate of this bug. *** (In reply to Mika Kuoppala from comment #1) > Do the gem_caching clients disappear if you wait long enough? > > While the clients are still there, does 'strace -p <gem_caching_pid>' show > any output? It only happens on automation testing via piglit. I can't reproduce it manually. igt_gem_multi_bsd_sync_loop also has this issue.
