Explanation

At deallocate, a nonzero read intent count or write intent count was detected. An error in DB2® logic is probably responsible for this condition.

System action

A record is written to SYS1.LOGREC, and a SVC dump is requested. The thread is deallocated normally.

System programmer response

If you suspect an error in DB2, you might need to report the problem. For information about identifying and reporting the problem, see Collecting diagnostic data.

Problem determination

Collect the following diagnostic items:
  • Console output from the system on which the job was run, and a listing of the SYSLOG data set for the period of time that spans the failure.
  • Dynamic dump, taken to SYS1.DUMPxx data set, by DB2 (04E and 04F abends).
  • Listing of SYS1.LOGREC data set, obtained by executing IFCEREP1.
  • Detailed description of events immediately prior to and during the abend.
  • SYSPRINT output, including JCL, for the application program or batch job, and system messages that were issued. Make sure that MSGLEVEL=(1,1) on the JOB statement so that all diagnostic information is sent to SYSPRINT.
  • DB2 log output, including any DB2 recovery log archive tapes.
