[curl:bugs] #1427 Facing 'Operation Timeout' issue with libcurl

Is there then a particular fixed limit where it stops working? 4.5MB works you say and 5MB doesn't, what about 4.7MB? 4.55? 4.51? Does it always fail on the big sizes or does it happen intermittently?

It works with an older libcurl you say, but doesn't that older libcurl also use a different TLS library version? Perhaps even a different TLS library?

When curl is talking TLS, all the actual TLS communication is done by the TLS library so if that fails there are not a lot of immediate remedies that I can think of...

Hi 
i am working for one of the cisco products, where we are using libcurl to send messages (wav file) to Exchange Server. we are using libCurl version 7.30 right now. With this version, when we try to send message of size >= 5MB (to exchange 2010, SP2) we are getting timedout error. i explored few more versions of libcurl and analyze that timeout issue was not there till version 7.23, it got introduced after that. Latest libcurl version 7.38 also has the same issue.
We have configured libcurl timeout to '15 seconds' and while sending the data (of nearly 5MB) getting following error message:
"HTTP request failed with error: Timeout was reached -- Operation timed out after 15003 milliseconds with 0 bytes received".
Can anyone suggest, and provide some help.
