 In my original description of how to reproduce, I didn't mention that 
 the syslog lines should include a loop counter to avoid the telescoping 
 of repeated lines.  Here is a test program:
 
 #include <sys/syslog.h>
 
 main(argc, argv)
 int argc;
 char **argv;
 {
 char *name;
 int i, maxi;
 
          maxi = atoi(argv[1]);
          name = (char *)strdup(argv[2]);
          for (i=0; i<maxi; i++) {
                  syslog(LOG_INFO,"%s %d",name,i);
          }
 }
 
 
 Invoke something like
 	test 1000000 aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa &
 	test 1000000 aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa &
 	test 1000000 aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa &
 	test 1000 bbbbbbbbbbbbbbbbbbbbbbb
 	killall test
 	grep bbbbb /var/log/message | wc
