Description Fabio Massimo Di Nitto 2012-02-06 15:49:14 UTC

2 node cluster
start corosync on both
allow it to settle down
start dlm_controld -f0 -D on both nodes at the same time, in some cases, dlm_controld will hang in some _initialize call.

It appears somekind of race condition, the problem is that running gdb dlm_controld will not trigger the problem.
