[pve-devel] Error cancelling global ust listener thread

[Dietmar Maurer]

I get strange warning after installing ceph packages on pve 4.0beta2

# pveceph install

after that, a simple 'qm start <vmid>' produces:

# qm start 102
Running as unit 102.scope.
libust[11943/11943]: Error: Error cancelling global ust listener thread: No such
process (in lttng_ust_exit() at lttng-ust-comm.c:1592)
libust[11943/11943]: Error: Error cancelling local ust listener thread: No such
process (in lttng_ust_exit() at lttng-ust-comm.c:1601)


Any idea what produces those libust warnings?
