We used pegasus 2.0 and pegasus_shell disk_capacity command to query cluster
disk's Usage
sometimes disk_capacity -d cause crash, sometimes cause infinite loop, it
Occurs occasionally.
I tracked the pegasus_shell dead and cpu 100% when i frequent use
disk_capacity -d
the stack roughly as follows：
------------------------------
#0 in std::_Rb_tree_increment(std::_Rb_tree_node_base const*)
#1 in std::_Rb_tree_const_iterator gcc10/include/10.2.0/bits/stl_tree.h:376
#2 in std::_Rb_tree stl_tree.h:2531
#3 in std::_Rb_tree stl_tree.h:2542
#4 in std::map stl_map.h:1069
#5 in call_rpcs_sync replication_ddl_client.h:306
