1439.1not a resource problemDRAGNS::WHEATERFri May 02 1997 18:2110
    This is not related to a resource problem. This is an assertion failure
    in the db_compression routine that writes the checkpoint file. In this
    case the nodes in do not equal the nodes written.

    This problem rarely occurs and I would suggest that you ignore it
    unless it become more frequent.

1439.2BUG CHECK OCCUR AT EACH START OF THE DNS SERVERPRSSOS::MONZONTue May 06 1997 15:1710
	Hello,

	we need a workaround, if possible, because at this customer site, there 
   are five DNSserver. And on two of these servers this BUGcheck occur at each 
   DNSserver STARTING. 
	These two DNSserver are down.

	THANKS IN ADVANCE.
	REGARDS
	JEAN-LOUIS MONZON.
1439.3may require surgeryTECMAN::WHEATERWed May 07 1997 19:3627
Hi Jean-Louis:

    Please run the surgeon over the checkpoint files of the servers that
    are bugchecking. Use the -scanrx and -scand options.

    Check for the word "corruption" in the -scanrx output. Also check
    that the number of directories in the -scand output is equal to
    the number of directories in the header.

    You may want to use the lastest version of the surgeon:


	dragns::user$91:[wheater.public]dns_db_surgeon.c


    compile is using VAXC (as we have had problems with decc in the past).


    If you have corruption you can remove the bad directory with the
    "excised" command or is the directory count is bad it can be adjusted
    by using the "changed" command.

    if you have neither  problem or don't understand how to correct the above
    problems you should submit an IPMT.

    Regard,
    Bob Wheater

        I ran SURGEON process over the checkpoint files of the servers that
  are bugchecking using the -scanrx and -scand options without problem.

        I will submit an IPMT.

        and many thanks for your help.
