Yes.

This is a Unix signal (and not an exception in the pascal sense) which is not caught by the FPC rtl.
You should (when sending data to your socket) add the MSG_NOSIGNAL flag to fpSend (on Unix).

Have a look in fcl-web/src/base/custfcgi.pp to see how we do this.

(and look on internet for the meaning of the  MSG_NOSIGNAL flag :) )
