I have installed ATS 6.1.0 as tr-full for caching my clients Web Traffic on
port 80 this week and every thing works fine. but while I'm looking
statistics i found something abnormal about* 35% Error-Total*:

as you can see above statistics, *Client-aborted* is taking many
*Byte-Percent* and *Invalid-request* is taking many *Count-percent*.
do you have any idea about this? are there any config parameters to reduce
these error counts?

i change some configs like below:
##############################################################################
# HTTP connection timeouts (secs). Docs:
#
https://docs.trafficserver.apache.org/records.config#http-connection-timeouts
##############################################################################
#CONFIG proxy.config.http.keep_alive_no_activity_timeout_in INT 115
CONFIG proxy.config.http.keep_alive_no_activity_timeout_in INT 3600
#CONFIG proxy.config.http.keep_alive_no_activity_timeout_out INT 120
CONFIG proxy.config.http.keep_alive_no_activity_timeout_out INT 900
CONFIG proxy.config.http.transaction_no_activity_timeout_in INT 30
CONFIG proxy.config.http.transaction_no_activity_timeout_out INT 30
#CONFIG proxy.config.http.transaction_active_timeout_in INT 900
CONFIG proxy.config.http.transaction_active_timeout_in INT 14400
#CONFIG proxy.config.http.transaction_active_timeout_out INT 0
CONFIG proxy.config.http.transaction_active_timeout_out INT 14400
CONFIG proxy.config.http.accept_no_activity_timeout INT 120
CONFIG proxy.config.net.default_inactivity_timeout INT 86400

but it didn't removed the problem completely.
