Hi Eril,
kindly let me know this dump is occurring for z*program or any other standard program. let me know the details. If its Z*program than followup with user there must be a recent variant implemented in system and searching for million of records. check with ABAPers to split the variant for the same. This might be also temporary bottleneck neck ask run the job in background and check the same.
Give more details on this issue.
Thanks,
Brindavan
