I need to wrap up this investigation for today, but I just ran the following test under valgrind:memcheck:
Start Ganesha using valgrind Mount v4 export Create 10,000 directory entries in /mnt4/test1/many Issue rm -rf /mnt4/test1/many Ctrl-c to terminate. As an aside note: for FSAL_VFS we may have a file descriptor issue somewhere, running with the default 1024 file descriptors is not sufficient... Here is one worrying allocation backtrace: ==3123== 9,216 bytes in 9 blocks are possibly lost in loss record 410 of 430 ==3123== at 0x4C28BF6: malloc (vg_replace_malloc.c:299) ==3123== by 0x4879B9: gsh_malloc__ (abstract_mem.h:78) ==3123== by 0x48CBA6: nfs4_FSALattr_To_Fattr (nfs_proto_tools.c:3593) ==3123== by 0x48C89B: file_To_Fattr (nfs_proto_tools.c:3496) ==3123== by 0x46543C: nfs4_op_getattr (nfs4_op_getattr.c:133) ==3123== by 0x45EEEF: nfs4_Compound (nfs4_Compound.c:743) ==3123== by 0x44B055: nfs_rpc_execute (nfs_worker_thread.c:1291) ==3123== by 0x44B86C: worker_run (nfs_worker_thread.c:1563) ==3123== by 0x505EF4: fridgethr_start_routine (fridgethr.c:550) ==3123== by 0x668B609: start_thread (in /usr/lib64/libpthread-2.22.so) ==3123== by 0x7010A4C: clone (in /usr/lib64/libc-2.22.so) That should have been cleaned up, and if some number of getattr are leaking memory, then that's really bad... All other losses I see look like just not cleaning up all the exports, and perhaps especially not cleaning up the PseudoFS properly. We may also not clean up all the threads on exit. I will look into this more next week if someone else hasn't already.
