data of size nearly 4.5 MB is getting sent off completely but not the larger ones. i also tried while keeping timeout value to 30 sec but result is still the same. If use libcurl version 7.23 (or 7.22) things workk fine. Problem seems to be introduced in later versions. Facing the same issue with lastest version 7.38 as well.

i am using red hat as OS and sending data to Windows Server (Microsoft Exchange 2010 installed on it). TLS version used is 1.2

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.
