Configure bwlim-out traffic limit per whole backend (not per single backend server)

Help!
1

Hello!!
I try to set outgoing traffic limit to whole backend (webserver80_443_to_webserver80_back), work almost as I wish, but when I start to curl one file from multiple client and if I break getting this file from any client (CTRL+C) on other clients downloading is freezing and usualy breaking downloading too (occasionally, after couple of minutes they continue downloading, but it happen rarely)
My config file :
backend sticktablelimit
stick-table type string size 1m expire 3600s store bytes_out_rate(1s)

backend webserver80_443_to_webserver80_back
filter bwlim-out backendlimit key be_name table sticktablelimit limit 25m min-size 2896
http-response set-bandwidth-limit backendlimit
http-request track-sc0 be_name table sticktablelimit

Does anybody knows why this freeze happen or better how to make limit by whole backend in right way?

I solve this problem:

backend sticktablelimit
stick-table type string size 1m expire 3600s store bytes_out_rate(1s)

backend webserver80_443_to_webserver80_back
filter bwlim-out backendlimit key be_name table sticktablelimit limit 25m
http-response set-bandwidth-limit backendlimit

Solved!!(http-request is wrong here for my goals).
