ECO KIT SUMMARY:
An ECO kit exists for F11BXQP on OpenVMS Alpha V7.0. This kit
addresses the following problems:
PROBLEMS ADDRESSED IN ALPF11X04_070 for OpenVMS Alpha V7.0:
o An XQPERR bugcheck occurs when trying to create a file.
o Bad FID bugcheck when trying to mark a file header free in the
index file bitmap.
o There are multiply allocated blocks and file headers on the
disk.
o The contents of a header or bitmap block could be corrupted
within the block buffer cache.
o Failure to take an allocation lock could be ignored.
o If a DEACCESS request failed with a SS$_DEADLOCK error, a
process could be left in RWAST state indefinitely.
o If a large file is created on a fragmented disk that has quotas
enabled and the user needs to use EXQUOTA privilege to allocate
the necessary disk space, an internal XQP table can become
corrupted. This leads to the following bugcheck:
SECAUDERR, Fatal error attempting to perform a security audit
o Superseding a file with a version limit set can remove the
oldest version of a file, even if that version is undeletable
by the user according to its protection mask or ACL. The file
is removed but not deleted, and can be recovered by
ANALYZE/DISK/REPAIR.
o Attempting to queue a maximal length (39.39;5) filename to the
XQP for spooling to a symbiont would cause either an infinite
CPU loop or a FILCNTNONZ, Open file count nonzero after process
rundown bugcheck.
PROBLEMS ADDRESSED IN ALPF11X01_071 KIT FOR OpenVMS Alpha V7.0:
o The problem occurs when a file is deleted while still being
accessed by someone. This produces an XQPERR bugcheck when an
attempt is made to access the deleted file.
o The problem may result in an XQPERR bugcheck which claims that:
"all the index buffers are active" during the processing of a
directory file.
The problem occurs when no free directory index BFRD's are
found on the first pass through MAKE_DIRINDX. The thread then
stalls to allow some of the BFRD's to be freed, but doesn't
release the cache lock which would allow others to do this.
This means that if no free BFRD was found on the first try then
none will be found on subsequent tries either, and the bugcheck
will occur.
o The fault occurs as a UNXSIGNAL Bugcheck after running AUTOGEN,
and rebooting with very large SYSGEN ACP cache parameters.
The problem occurs when the calculation of DIRINDX in
RELEASE_LOCKBASIS overflows. This is due to a multiplication
taking place before a division, which overflows when more than
87381 blocks have been allocated between the ACP_MAPCACHE,
ACP_DIRCACHE and ACP_HDRCACHE caches.
PROBLEMS ADDRESSED IN ALPF11X03_070 KIT for OpenVMS Alpha V7.0:
o BACKUP and SLS can cause WCBFCBMNG bugchecks when operating on
some files. These files are legal, uncorrupted files so they
should not repeatedly cause a crash whenever BACKUP or SLS
tries to back them up.
o A system could crash with a SECAUD bugcheck whenever
ANAL/DISK/etc is run on a corrupted disk with auditing turned
on.
o The XQP bugchecks when a file is accessed for the first time,
with cathedral windows, and the accessing process runs out of
BYTLM quota.
o Window mapping code could incorrectly concatenate extents which
ran from one volume to another in a volume set.
o XQPERR bugcheck in [F11X]DIRSCNuPDATE_INDEX() when trying to
insert index entry into directory index block with
DIR$W_TOTALCELLS equal to zero.
o Directory FCBs can become stale but invisible to the XQP. The
File IDs can then be reused, and if the FCB in question was an
extension FCB, the next time the new file is accessed on that
node, the XQP bugchecks with the fatal XQPERR 'wrong lockbasis
with FCB present'.
o If a file is opened for exclusive access on one node in a
cluster and a BACKUP/IGNORE=INTERLOCK command is issued to
backup the file on that node, after the BACKUP completes the
file can be successfully accessed from the other node(s) of the
cluster. The BACKUP destroys the exclusive access.
PROBLEMS ADDRESSED IN ALPF11X01_070 KIT for OpenVMS Alpha V7.0:
o When enabling quotas on the system disk, the system
occasionally crashes with an ACCVIO.
o File name appears twice in a directory block.
o System crashes with a BADDALRQSZ bugcheck
o Multiple allocated blocks being reported after the defragger
has been run.
o UNXSIGNAL crash due to a corrupt Window Control Block
o File Access Control Lists are corrupted after a failure to
allocated an extension File Control Block due to disk quota
being exceeded.

ECO KIT ORDERING INSTRUCTIONS:
If after an evaluation you wish to obtain this kit, request it
electronically using the appropriate Advanced Electronic Services
(AES) Service Tool. If you are not familiar with how to request
kits electronically, open the DIA, WIS or DSNLINK database and
review the article entitled:
[AES] How To Electronically Request ECO Kits Using Service Tools
INSTALLATION NOTES:
In order for the corrections in this kit to take effect, the system must
be rebooted. If the system is a member of a VMScluster, the entire
cluster should be rebooted.
