Bad emulation
I am using mpc8xx processor with linux-2.4.20 kernel. These prints are getting flooded to my console almost consistenly.
Code:
 14 06:29:17 MC4L-TP01 syslog.warn klogd:  pte @ 0x10113d88:  (0xc51cc100)->(0xc4bd144c)->0x01eec889

Oct 14 06:29:19 MC4L-TP01 syslog.warn klogd: Bad emulation nm.d/773

I am concerned over the "Bad Emulation" print. Does it appear if we use floatng points in our application softwares as mpc8xx is not equipped to handle floating points?
Is there a fix for this ? Will compiling the application s/w with some appropriate flags solve this issue??

Thanks in advance.!

warn.conf

warn.conf(4)							   File Formats 						      warn.conf(4)

NAME

       warn.conf - Kerberos warning configuration file

SYNOPSIS

       /etc/krb5/warn.conf

DESCRIPTION

       The  warn.conf file contains configuration information specifying how users will be warned by the ktkt_warnd daemon about ticket expiration
       on a Kerberos client. Credential expiration warnings are sent, by means of syslog, to auth.notice. All other warning messages are  sent	to
       daemon.notice.

       Each  Kerberos  client host must have a warn.conf file in order for users on that host to get Kerberos warnings from the client. Entries in
       the warn.conf file must have the following format:

       principal syslog | terminal | mail time [email_address]

       principal       Specifies the principal name to be warned. The asterisk (*) wildcard can be used to specify groups of principals.

       syslog	       Sends the warnings to the system's syslog. Depending on the /etc/syslog.conf  file,  syslog  entries  are  written  to  the
		       /var/adm/messages file and/or displayed on the terminal.

       terminal        Sends the warnings to display on the terminal.

       mail	       Sends the warnings as email to the address specified by email_address.

       time	       Specifies  how  much  time before the TGT expires when a warning should be sent. The default time value is seconds, but you
		       can specify h (hours) and m (minutes) after the number to specify other time values.

       email_address   Specifies the email address at which to send the warnings. This field must be specified only with the mail field.

EXAMPLES

       Example 1: Specifying warnings

       The following warn.conf entry

       * syslog 5m

       specifies that warnings will be sent to the syslog five minutes before the expiration of the TGT for all principals. The form of  the  mes-
       sage is:

       jdb@ACME.COM: your kerberos credentials expire in 5 minutes

FILES

       /usr/lib/krb5/ktkt_warnd        Kerberos warning daemon
