help: problem with sockets write/read

I am trying to make a server and client, the client will choose between some options and the server will react accordingly.

After a some reads and writes that work the server needs to read from client an INT i use this:

Code:
read(newSd,&k,sizeof(int));

But even if all the other times there was no problem
this time the server does not seem to block on read OR it reads something but without the client sending.I also wrote multiple reads in server after this one and no writes in client, still the server passed through them to the next lines of code.

What could cause this?

NAME
bup-server - the server side of the bup client-server relationship SYNOPSIS
bup server DESCRIPTION
bup server is the server side of a remote bup session. If you use bup-split(1) or bup-save(1) with the -r option, they will ssh to the remote server and run bup server to receive the transmitted objects. There is normally no reason to run bup server yourself. MODES
smart In this mode, the server checks each incoming object against the idx files in its repository. If any object already exists, it tells the client about the idx file it was found in, allowing the client to download that idx and avoid sending duplicate data. This is bup-server's default mode. dumb In this mode, the server will not check its local index before writing an object. To avoid writing duplicate objects, the server will tell the client to download all of its .idx files at the start of the session. This mode is useful on low powered server hard- ware (ie router/slow NAS). FILES
$BUP_DIR/bup-dumb-server Activate dumb server mode, as discussed above. This file is not created by default in new repositories. SEE ALSO
bup-save(1), bup-split(1) BUP
Part of the bup(1) suite. AUTHORS
