How about driving some of them with fanout records? Only one scan per fanout then.

Or an FLNK chain...
Well, FLNK may not work this case.
recGblFwdLink() is a last function call in the process() function of every record. So caller of recGBlFwdLink() stays on the stack until
completion of remaining FLNK.

Subject: scan task stack overflow


Hi,

We have overflowed the stack of the scan5 task by putting too many records at a 5 second scan rate. What is the best way to handle this situation? Aside from reducing the number of records.

Thanks, Geoff
