What measures should be taken to prevent process termination by SIGPIPE signal when using long killer?

To prevent process termination due to the SIGPIPE signal when using long killers (for example, when working with Unix sockets or pipes), you need to:

1. Handle the SIGPIPE signal in the application, for example, by ignoring it or overriding the handler so that the process does not terminate automatically.

2. Check the return values of system calls like write, as writing to a closed channel can cause an EPIPE error.

3. Use flags or options that suppress SIGPIPE generation, for example, in Linux, you can use the MSG_NOSIGNAL flag with send() for sockets.

Example of ignoring SIGPIPE in C (similarly, it can be done in other languages):

#include <signal.h>

signal(SIGPIPE, SIG_IGN); // Ignore SIGPIPE signal

Thus, the process will not terminate when attempting to write to a closed channel, and errors can be handled programmatically.
