Status: Closed |
UPDATE STATISTICS MAY RESULT IN ASSERT FAILURE IN HASHFULLNAME WHEN REFERENCING FREED DATA DICTIONARY ENTRY FOR TABLES USING REF |
| product: |
INFORMIX SERVER / 5725A3900 / B70 - IDS 11.70 |
| Problem description: |
When running update statistics in a database containing tables
with referential constraints it is possible that an AF with a
stack similar to the following may occur if a reference is made
to a freed data dictionary entry that has been re-used.
afstack
mt_ex_throw_sig
afsig_handler
hashfullname
getddhptr
getshdicptrx
fndiccp
checkrefdicp
verrefinfo
blddicref
bldrefsx
bldrefs
maybe_bldrefs
ip_sqloptim
ip_sqloptim
cmp_stmt
cmp_proc
pr_compile
aud_pr_compile
updprocstat
excommand
sq_execute
sqmain
listen_verify
spawn_thread
th_init_initgls
startup
This stack is an example from an instance running the update
statistics for procedure command.
References to freed data dictionary entries are normally
intercepted and handled appropriately however depending on the
content of the re-used memory block there may be specific
patterns which are not handled correctly resulting in the above
AF. |
