Some older versions of Solaris are susceptible to an occasional ENXIO failue
for the ioctl(TIOCSWINSZ) in server-client.c, which leads to a tmux server
failure. There is already a comment here about one such TIOCSWINSZ failure on
Solaris:
~~~~~
#ifdef __sun
/*
* Some versions of Solaris apparently can return an error when
* resizing; don't know why this happens, can't reproduce on
* other platforms and ignoring it doesn't seem to cause any
* issues.
*/
if (errno != EINVAL)
#endif
~~~~~
The following client script may demonstrate the ENXIO failure:
~~~~~
while sleep 1; do tmux split-w 'sleep 1; exit'; done
~~~~~
The attached patch addresses the server failure, with no apparent issues. Will
update this ticket when more is known about the core reason for the ioctl()
failure.
