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?

GEMS-CLIENT(1)							gems documentation						    GEMS-CLIENT(1)

NAME
gems-client - Show data transmitted by gems-server (1) SYNOPSIS
gems-client [-i] host [port] gems-client -h | -v DESCRIPTION
Connects to a computer running gems-server(1) to show in the local terminal the data transmitted, in real time. OPTIONS
host Hostname or IP address where the server is running. port TCP port used by the server. Default: 6666. -i Ignore server terminal size. If this option is not supplied, gems-client disconnects itself whenever the local terminal is smaller than the terminal associated to the server. -h Show a short help message. -v Show version information. FUNCTION KEYS
While gems-client is running, some keys have special functions: q Quit. a Enable/disable alarm blocking. When active, if the server transmits an alarm character ('a'), the client ignores it, so the alarm does not play. This is specially useful when many clients are present in the same room, to avoid the annoying simultaneous beeps. AUTHORS
