Error description
After ABENDx37 there can be IEC999I message(s) and ABENDD78 or ABEND0C4 in DIV. When cleanup is attempted IFG0TC0A runs the TCB/DEB chain to Close any OPEN DCBs. If the DCBs were part of a PDSE module, which is under DIV control the resource manager is called prior to IFG0TC0A, so the DCB storage has been zeroed. IFG999I messages with a -1 after the DEB address indicating the DCB is unavailable. If a subsequent DEB is to processed it is possible that a CLOSE will not be issued if the DCBOVLAY bit has been set. This will result in PDSE(s) not being properly Closed and ABENDD78 or ABEND0C4 in DIV.

Problem summary
**************************************************************** * USERS AFFECTED: All. * **************************************************************** * PROBLEM DESCRIPTION: ABENDD78 or ABEND0C4 in DIV. * **************************************************************** * RECOMMENDATION: * **************************************************************** At task termination, IFG0TC0A runs the TCB DEB chain and issues SVC20 CLOSE against the DCB/ACB pointed to by each DEB. One of these DEBs points to a PDSE DCB page loaded into DIV storage. The DIV resource manager gets control prior to task close freemains and zeros the DCB storage. This results in IEC999I...DEBADDR-1 indicating the DCB storage was freemained. IFG0TC0A incorrectly does not issue CLOSE against the DCBs pointed to by the subsequent DEBs in the chain. If one of these DCBs is for a PDSE paged loaded into DIV this subsequently leads to abendd78 or abend0c4 in DIV.
Problem conclusion
In the above scenario Task Close will continue to issue CLOSE against the DCBs pointed to by subsequent DEBs in the chain.
