Hello Tejasv,
it looks like you may be encountering the issue discussed in :
810957 You receive more than one "400 bad request" response to one HTTP
request
<a style='text-decoration: underline;' href="http://support.microsoft.com/?id=810957" target="_blank">http://support.microsoft.com/?id=810957</a>

Modifying the "uploadreadaheadsize" may help
