I'm using Ganesha 2.6 dev.12 with jemalloc-3.6.0 and hitting a case where jemalloc seem to be holding a lock and crashing. In Ganesha's gsh_backtrace(), we try to allocate memory and that hangs (ended up in deadlock). Have you seen this before? Perhaps it is a good idea not to allocate memory in backtrace path?
