Hi Andrew,
I changed cluster option to batch-limit=3,I re-tried it.
However, similar time-out occurs.
I measured processing just before the time-out(120s) in systemtap.
The following only the function long time.
-----
probe start! ---------------------------------
cib_process_request [call-count:179][117,540,173,155 nsec]
cib_process_command [call:179] [116,471,047,275 nsec]
cib_process_command call function ---
cib_config_changed [call:179] [101,169,909,572 nsec]
cib_config_changed call function ---
calculate_xml_digest [call:179] [ 68,820,560,745 nsec]
create_xml_node [call:3012263] [ 19,855,469,976 nsec]※
xpath_search [call:179] [ 145,030,232 nsec]
diff_xml_object [call:179] [ 32,677,359,476 nsec]※
calculate_xml_digest call function ---
sorted_xml [call:1505799] [ 52,512,465,838 nsec]※
copy_xml [call:179] [ 3,692,232,073 nsec]
dump_xml [call:536] [ 6,177,606,232 nsec]
-----
Is there the method to make these processing early?
