Didn't find something obvious within the same process (that does `zil_commit_impl` in one thread). The committing process is Buildbot, and I= saw that it happened during a nightly run of periodic scripts (which go through whole filesystem). Now I have to reboot the instance... That's why a non-destructive debugging method might be more helpful to see what other interlock we have between processes/threads. --=20 You are receiving this mail because: You are on the CC list for the bug.=
