Unable to upload file with curl when --limit-rate is set to specific value

[TKTim]

I did this

This command is for upload a xml file on to my server's interface.
Server is using C# .Net MVC.

bash -c 'curl --connect-timeout 10 -H "Content-Type: text/xml; charset=utf-8"  -H "SOAPAction:http://tempuri.org/UploadProcessResult" -d @redhat9-1AA2.xml -o redhat9-1AA2_output.xml --limit-rate 100K -S -k http://192.168.30.5/SIP/Interface/Interface.asmx'

I expected the following

  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100  432k  100   393  100  431k      9  10189  0:00:43  0:00:43 --:--:--  9762

• The file is 600 KB
• When I remove " --limit-rate 100K ", It succeeds.
• When I change " --limit-rate 100K " to " --limit-rate 10K ", It succeeds.
• When I change " --limit-rate 100K " to " --limit-rate 1000K ", It succeeds.
• When I change " --limit-rate 100K " to " --limit-rate 200K ", It fails.

Note that you are using a three year old curl version.

Since e492c7c we have test cases verifying this functionality, which indicates that current curl supports this fine.

@bagder Thanks for the reply, I will give the new version a try.

Presumed to be fixed already.
