	after running a ktrace on a Linux binary, I get a 7MB ktrace.out
	file.  

>Description:

	running kdump on this output file, it fails with Cannot allocate memory
	after accessing the last break call .  Here is the kdump on the kdump:

Jim.Pirzyk@snoopy:/usr/src/usr.bin/kdump
46>kdump | grep break
 56504 kdump    CALL  break(0x804e000)
 56504 kdump    RET   break 0
 56504 kdump    CALL  break(0x804f000)
 56504 kdump    RET   break 0
 56504 kdump    CALL  break(0x8051000)
 56504 kdump    RET   break 0
 56504 kdump    CALL  break(0x8052000)
 56504 kdump    RET   break 0
 56504 kdump    CALL  break(0x8054000)
 56504 kdump    RET   break 0
 56504 kdump    CALL  break(0x808b000)
 56504 kdump    RET   break 0
 56504 kdump    CALL  break(0x7d772000)
 56504 kdump    RET   break -1 errno 12 Cannot allocate memory

>How-To-Repeat:

	I can send the ktrace.out file, but compressed, it still is over 1MB.

 This may be caused by breakage of atomic writing of ktrace records in
 rev.1.37 of kern_ktrace.c.  Perhaps there is only a problem when the
 ktrace output file is on an nfs filesystem.  There must be multiple
 processes writing to the same file to cause problems.

Closed since now I should be using linux_kdump instead of just 
kdump.
