Resolution

The new OPSLOG archive process (post R13.0) internally calculates the amount of space in tracks needed to copy the number of OPSLOG records for the current archive request and then passes this amount on the internal start command.  The total space calculated for the archive is divided by 16 and that amount is specified as the primary and secondary amounts to avoid a conflict with SMS for storage constraint relief classes and a rejected request if the requested volume/s do not have the entire needed space in a contiguous area. 

Look at the dataset that was allocated for the archive request that received the B37 abend.  There was not enough space on the volume to handle the request - 223 tracks x 16 extents= 3568 tracks; only 2007 tracks were allocated/available on volume 1EG004.  Based on the manual archive execution of the same data, 13 extents is what would have been needed on the failing request to accommodate the archive request.  So the total space needed was not available at the time of the request on volume 1EG004.
