Is there any limit on the size of the data, while creating Trello card using Trello API post request

[Choudam.Raghu.Rambabu]

While creating Trello Card by invoking the post request ( https://api.trello.com/1/cards?)  (Trello card having description of size more than 10 or 11 KB)  i am getting "upstream connect error or disconnect/reset before headers. reset reason: connection termination" error

That doesn't look like a generic Trello API error - my best guess is that Trello was having an outage. 10 or 11 KB description should be fine.
