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

       the  command  source  with the Tty parameter. Output is then restricted to the specified parameters. A Tty terminal may be named fully (for
       example, tty0) or abbreviated (for example, 0).

       The following information is displayed for each process: Name of the command under which the process was called.  Any flags collected  when
       the  command  was  executed.  The following flags are valid: Command was run with an effective user-id of 0.  Command ran after a fork, but
       without an exec system call following it.  Name of the user who issued the command.  The terminal the command was started from.	Seconds of
       CPU time used.  Time the process started.
