Hi Marco,
Please contact IBM support with a small snippet of code.
Especially any Data Structures using ALIGN(*FULL) and LIKEREC(<prototyped value>); If it's a common issue in your source code, it's likely in a /copy or /include file.
I suspect these occurred in 98 as well, but that stack trace will fill up logs very quickly.
Thanks!

Looks like RDi 9.9 is still generating the RCL_API_Log_Sample xml files.
The latest file is locked by the process so it can't be deleted
without shutting RDi down.
