Backtrace of core
I suspect it is due to creating of multiple threads in every distribute init(). This is fixed by qa44. Can you confirm? I tested it my self. I noticed that the crash is comming because of nested lock or something similar. The client side issue of distribute sync env thread is not the issue here.. More debugging happening. http://review.gluster.com/3493 fixes the issue. Currently only on upstream, on need basis, will be backported to release-3.3 branch. the bug fix is only in upstream, not in release-3.3. Hence moving it out of the ON_QA, and setting MODIFIED (as a standard practice @ Red Hat) |
