ABSTRACT OF PROBLEM
___________________
BLOG  may  cause  a  CTL-6E8  while attempting to file a release
block during pool cycle down.
 

COMMENTS ON PROBLEM
___________________
When CCSONP fills a CA  block  with  release  file  requests  it
issues  CXFRC  to BLOG to file these releases to the appropriate
RC8RFS record.   BLOG receives the block  and  acquires  a  pool
address  into  which the CA will be filed.  If GFS becomes inac-
tive between the time of the CXFRC  and  the  time  BLOG  issues
GETFC, BLOG takes a CTL-6E8 on its error path.
 
Following   the  detection  of  GFS  inactive,  the  error  path
attempted to acquire a block on D9 to keypoint the current FC33.
This level may have already been holding a block, depending upon
where in the code 'GFS inactive' was determined.
 
 

SOLUTION
________
To fix this, before proceeding down the error  path,  if  D9  is
holding a block it is released.  Also a check for GFS is made at
the start of processing of the release block.
 
If  not  active  the block is processed as though it were a 1052
state release.
