Hello, I have a problem with an application I wrote. It works fine under Solaris, Linux, and FreeBSD till release 5.2.1. Under FreeBSD 5.3 and newers I have problems. The application is constituted by two processes : a supervisor and modules. The supervisor forks and become a module when it shall launch one. The supervisor is a single loop and it has a thread to handle signals. Each module is a multithreaded server, with its own thread to handle signals. Under FreeBSD 5.3 and newers, when the supervisor forks to become a module, it receives a SIGABRT and exits immediately when it launches the signal handler thread. I solved this by replacing the signal handling of the father : using a handler defined with sigaction instead of using a thread. But I'd like to understanding what's wrong with this and what changed from FreeBSD 5.2.1 to 5.3 Thanks Jose-Marcio
