Error description
You have tasks waiting for file buffers, resource name FCBFSUSP. During CICS shutdown, a CESD task issues a forcepurge for each of these tasks. But before these tasks get a chance to be dispatched and start purging, DFHFCVS, proc BUFFER_RELEASE, issues RESUMEs for all of these tasks while executing on behalf of another task that was terminating and so freeing the buffer. As each of these tasks gets dispatched, they get a PURGED response (due to the CESD purge), and so now a second RESUME is issued. This will cause the CICS Dispatcher to subsequently issue the error: . DFHDS0002 A SEVERE ERROR (CODE X'0056') HAS OCCURRED IN MODULE DFHDSKE. . The trace shows an accompanying exception entry: . DS 0056 DSKE *EXC* - DSKE_TASK_SUSP_TOK_IN_USE . The problem is very similar to PK86217 except that the tasks here are waiting on file buffers, not exclusive control conflicts. .

Problem summary
**************************************************************** * USERS AFFECTED: All CICS Users. * **************************************************************** * PROBLEM DESCRIPTION: MsgDFHDS0002 severe error * * (code X'0056') occurs in module * * DFHDSKE. * **************************************************************** * RECOMMENDATION: * **************************************************************** DFHDS0002 A severe error (code X'0056') has occurred in module DFHDSKE is issued, along with exception trace entry: DS 0056 DSKE *EXC* DSKE_TASK_SUSP_TOK_IN_USE. If a task is waiting in File Control for a VSAM Buffer then it may time out and be resumed by another task. A purged or timed out response at this point will cause a resume to be issued. The double resume can cause problems later, for instance the next suspend may be resumed immediately. Additional Keywords: FCBFSUSP 0056 DS0056 DS0002
Problem conclusion
DFHFCVR has been amended to ensure a resume is only issued after a purged response if the task has not already been resumed by the task that was holding the resource.
