Jul 29, 2014 Interrupted system calls. Regardless, Python's signal. signal () function clears the SARESTART flag when setting the signal handler: all system calls will probably fail with EINTR in Python. Since receiving a signal is a nonexceptional occurrence, robust POSIX code must be prepared to handle EINTR (which, in most cases,

IOError: [Errno 4 Interrupted system call I don't know if this is a valid behavior or not, perhaps it's a bug inside Python signal handling, but anyway, why don't you just catch the exception? Dec 17, 2001 socket. error: (4, 'Interrupted system call') Why is error? How to correct it? Any ideas will be appreciated. You asked for SIGCHLD, it arrived during recv() and interrupted it. This would happen with C just as it would in Python. python socketserver interrupted system call Feb 17, 2007 IOError: [Errno 4 Interrupted system call; readlines() with large file raises: IOError: [Errno 12 Cannotallocate memory; IOError: [Errno 32 Broken pipe Interrupted function call exception while relogging: ( Interrupted function call exception in Python service while relogging 'Interrupted function call' in time. sleep(1000) after relogging

Interrupted system calls. On POSIX systems, signals are common. Code calling system calls must be prepared to handle them. Examples of signals: The most common signal is SIGINT, the signal sent when CTRLc is pressed. By default, Python raises a KeyboardInterrupt exception when this signal python socketserver interrupted system call The accept() call failing with EINTR is normal. Your child process ended, and the current system call is interrupted. This happens for a few system calls even when you set SARESTART in sigaction flags. You just continue the loop, trying to accept a new client, IOError: [Errno 4 Interrupted system call I don't know if this is a valid behavior or not, perhaps it's a bug inside Python signal handling, but anyway, why don't you just catch the exception? Thanks for contributing an answer to Stack Overflow! Please be sure to answer the question. Provide details and share your research! But avoid. Asking for The Python interface is a straightforward transliteration of the Unix system call and library interface for sockets to Pythons objectoriented style: the socket() function returns a socket object whose methods implement the various socket system calls. Parameter types are somewhat higherlevel than in the C interface: as with read() and write() operations on Python files, buffer allocation
