Epipe errors seen in log files

This document (7003193) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 10

Situation

Epipe error messages are seen in log file.

Resolution

Please refer to man 7 pipe:
     
If all file descriptors referring to the write end of a pipe have  been closed,  then  an attempt to read(2) from the pipe will see end-of-file (read(2) will return 0).  If all file descriptors referring to the read end  of  a  pipe have been closed, then a write(2) will cause a SIGPIPE signal to be generated for the calling process.  If the calling process is  ignoring this signal, then write(2) fails with the error EPIPE.  An application that uses pipe(2) and fork(2) should use suitable  close(2) calls  to  close  unnecessary  duplicate file descriptors; this ensures that end-of-file and SIGPIPE/EPIPE are delivered when appropriate.
