Error description
We try to unload (IXB) a huge database record (over 180,000 segments) and we get a S0C4 abend in FMNMOD1 at offset x'A0AF6'. Note we get message "FMNBA009 Insufficient virtual storage available" twice with smaller REGION size. The IRT The IRT table grew larger than 4MB so the MVCL that FM/IMS uses to move it's contents couldn't handle its size.

Problem summary
**************************************************************** * USERS AFFECTED: All FM/IMS users. * **************************************************************** * PROBLEM DESCRIPTION: AbendS0C4 when using a view or criteria * * set with a selection criteria on a * * dependent segment. The problem occurs * * when the function reads a database * * record that has more than 409,600 * * segments. * **************************************************************** * RECOMMENDATION: Apply the provided PTF. * **************************************************************** When the view or criteria set has selection criteria on a dependent segment, FM/IMS reads to the end of the database record before it processes any of the segments in the record. It saves all the segments that satisfy the selection criteria in the Intermediate Record Table. If the table becomes full, FM/IMS creates a new one double the size and uses an mvcl instruction to copy the contents of the old table to the new table. When the database record is large, FM/IMS may have to double the table size several times. However, when the size of the old table exceeeds 16MB, the mvcl instruction does not copy all of the data to the new table. The abend occurs when FM/IMS attempts to process a table entry that the mvcl did not populate.
Problem conclusion
FM/IMS has been modified to correct this problem.
