our client_write_error is growing from time to time , but fail_xxxx are all zero

[root@AMZ]#  asadm --single_node_cluster -e "show statistics namespace" |grep 'fail'
fail_generation                       :   0

xdr_write_error                       :   0

how to identify what cause the write error ,I had try to set ‘rw-client=INFO’ ,but there is no error in log .

Not all errors have an individual stat and many common ‘errors’ do not log a warning at all (e.g. create-only when a record already exists increments this stat but doesn’t have an individual stat or a log warning). Would be hard to know what is causing this error without the error code that was returned to the client.

This may help: client_write_error and the article linked from that entry: Understanding Client Write Errors

Thanks you very much , after read the link , Cause I could not find any error message in server log , I think that our circumstances may be one of the list below , I am going to work with develop team to find more detail information from client return code.
