[NFS-Ganesha-Devel] Ganesha crash while doing Delegation recall

Hi, Currently seeing the following crash and it is a recurrent crash. We are using ganesha 2.8.4. Can someone please help in telling if this is a known issue and whether it is fixed in later releases ? (gdb) bt #0 0x00007fcc26df6570 in pthread_mutex_lock () from /lib/libpthread.so.0 #1 0x00007fcc2760906c in svc_rqst_expire_insert () from /lib/libntirpc.so.1.8 #2 0x00007fcc275f2e19 in clnt_req_callback () from /lib/libntirpc.so.1.8 #3 0x00007fcc27855c3e in nfs_rpc_call () from /lib/libganesha_nfsd.so.2.8 #4 0x00007fcc27856a13 in nfs_rpc_cb_single () from /lib/libganesha_nfsd.so.2.8 #5 0x00007fcc278837a4 in delegrecall_one () from /lib/libganesha_nfsd.so.2.8 #6 0x00007fcc27884422 in delegrecall_impl () from /lib/libganesha_nfsd.so.2.8 #7 0x00007fcc27886900 in queue_delegrecall () from /lib/libganesha_nfsd.so.2.8 #8 0x00007fcc278e6da9 in fridgethr_start_routine () from /lib/libganesha_nfsd.so.2.8 #9 0x00007fcc26df3f87 in start_thread () from /lib/libpthread.so.0 #10 0x00007fcc268755bf in clone () from /lib/libc.so.6 This seems like a channel is removed while it is being accessed by the backchannel.
