2007/11/09! 03.56.29! E00549! Enq_pty! Tty.c! 119! PID (22597)! Operations ioctl (TCS
helo,
i got accessing system from putty.

a user has had System Telnet up (for hours at a time) and been running various commands from the CUI menu.(its just client application) The following message appears over and over again in the account log:
2007/11/09! 03.56.29! E00549! Enq_pty! Tty.c! 119! PID (22597)! Operations ioctl (TCSETAW) failed,
file 'tty - errno 5: Input / output error

This problem is still happening. While the problem can be resolved, at least temporarily, by restarting all services.but I need to find out why this is occurring. The results vary slightly, but basically the client applications become unable to connect to the system.

what to do
Regards,
Amit

lyxclient

LYXCLIENT(1)							  lyxclient 1.6.5						      LYXCLIENT(1)

NAME

       lyxclient - send commands to a running LyX editor

SYNOPSIS

       lyxclient [ options ]

DESCRIPTION

       When  LyX  starts, it creates a unique, per-process local socket in the temporary directory through which commands can be sent. That is, it
       can act like a server, accepting connections from clients. lyxclient can be used as such client. lyxclient will take care of all connection
       and communication protocol details, leaving you (or your app) free to concentrate on what you want to send to LyX.

SERVER IDENTIFICATION OPTIONS

       lyxclient  must	first identify to which server (i.e. a running LyX) commands are to be sent. The following options are used to specify the
       server.

       -p pid
	     specify the pid of the running LyX process to which lyxclient should send commands.

       -a socket_address
	     specify explicitly which socket special file should be used. These special files are located inside lyx_tmpdir<lyx_pid><hash>, in the
	     temporary directory. There is one per running LyX process.

       -t tmp_dir
	     if LyX is configured to use a temporary directory other than /tmp, you must inform lyxclient of this.

       If  neither -a nor -p are invoked, lyxclient will search for sockets in /tmp (or tmp_dir if the -t option is used) and use the first socket
       to which it can connect.  This is safe if you are running only one LyX process at any one time.

COMMAND MODE OPTIONS

       lyxclient can send commands to LyX from both the command-line and from standard input.  LyX commands documentation can be found in LyX Help
       menu.

       -c command
	     send a single command, print LyX information to standard output and exit. LYXCMD prefix is needed in the given command.

       -g file line
	     this  is  simply  a  wrapper  for the command 'server-goto-file-row file line'. It is used by the DVI previewer to elicit inverse DVI
	     search.

       If neither -c nor -g are used, lyxclient will regard any standard input as commands to be sent to LyX, printing LyX's responses to standard
       output. Commands are separated by newlines (the '
' character). To finish communication and terminate the lyxclient process, send the com-
       mand 'BYE:'.

MISCELANEOUS OPTIONS

       -n name
	     when starting communication, lyxclient sends an idenfifier string to LyX. By default, this string is "PPID>PID", where PPID  is  lyx-
	     client's parent pid and pid is lyxclient's pid.  Use this option to override this default.

       -h    print the lyxclient version and summarize its usage.

ENVIRONMENT

       LYXSOCKET
	      can be used to specify the socket special file that must be used.  LyX sets this variable.  It is overridden by the -a option.

       lyx(1), xdvi(1), LFUNs.lyx.
