SIGTERM (15)SIGTERM (15) — Termination Signal
A graceful termination request was sent to the process.
EAGAINThe requested operation would block on a non-blocking resource, or a system resource is temporarily unavailable.
A non-blocking I/O operation could not be completed immediately. This also occurs when fork() fails due to insufficient system resources or when a semaphore operation would block.
Retry the operation after a short delay. For non-blocking sockets, use select(), poll(), or epoll() to wait for readiness. If fork() fails with EAGAIN, reduce the number of running processes or increase system limits.

EINTRA blocking system call was interrupted by a signal before it could complete.
SIGTTIN (21)A background process attempted to read from its controlling terminal.
Exit 143The process was terminated by SIGTERM (signal 15).
