Error description

• When online recovery feature is enabled (via DB2_ONLINERECOVERY
  registry variable), the rolling back of inflight transaction
  might be deferred during synchronous phase of database recovery.
  Insufficient log space was reserved for the deferred
  transaction, which can result in a failure to process the
  deferred rollback (due to log space being consumed by new
  transactions).

  DATA #1 : <preformatted>
  Force shutdown of database due to error during rollback
  processing.  Asynchronous Undo will be disabled for the next
  crash recovery.
  
  If you see the message above, this indicates that a subsequent
  attempt for crash recovery will not use the ONLINE RECOVERY
  feature which will avoid this problem.
  
  To prevent future occurrences of this problem, you can disable
  the ONLINERECOVERY feature: db2set DB2_ONLINERECOVERY=0
  

Local fix

• db2set DB2_ONLINERECOVERY=NO
