You do not need to prevent that. >Is there an undocumented requirement to single >thread multiple LOADs for the same module within a region? There is no such requirement. Only the first LOAD for a reentrant module (of multiple concurrent LOADs) will do the relocation. Subsequent LOADs for that module are delayed until the completion of the first LOAD. There have been occasional relocation bugs in the loader code for PDSE's, particularly when the relocatable item spans a page boundary (so it is not word aligned for a 4-byte item, or is not doubleword-aligned for an 8-byte item). Might your case fit into that situation?
