Re: snmpbulkwalk doesn't finish

hi dave,

ok, so here's how this section started (CISCO-FLASH-MIB):

ChecksumString ::= TEXTUAL-CONVENTION
         DISPLAY-HINT "x"
         STATUS  current
         DESCRIPTION
                 "Represents the checksum of a file.
                 "
         SYNTAX  OCTET STRING


and here's what it looked like after i made the change you suggested:

ChecksumString ::= TEXTUAL-CONVENTION
         DISPLAY-HINT "1x"
         STATUS  current
         DESCRIPTION
                 "Represents the checksum of a file.
                 "
         SYNTAX  OCTET STRING

and now snmpbulkwalk completes just fine, no hangs

i've backed out the change and replicated the hang


i found a paragraph on DISPLAY-HINT in Perkins/McGinnis ... but i don't 
think i'm wiser for it

anyway, if there's anything i can do to help you track this down 
further, plse let me know.  in any case, thank you for your assistance!
