nsIChannel Open() call goes into hanging state

Hi All,

Below code is getting hanged in linux and it is in blocking state.

nsIChannel *channel;

// Now, open the IO channel to an input stream form which we'll get the data
nsIInputStream *is;
rv = channel->Open(&is);


In above code Open() call is blocked and not coming out and application is in hanging state.


Is there any idea why in  Open() call is blocked ?


Thanks in Advance.
