The error was not stable, it required at least 3000-5000 dsects generated in activity summaries, no matter what was the type of the drilldown (plan, authid, etc.). The error happened in ISPF Datasharing mode only.
Problem conclusion
The fix removes the constraint to the number of retrieved records(dsects) and so removes error in ISPF client.
Temporary fix
