After the regular session close, I execute a program that accesses the L1 data, adding and dropping its way through all 3,300 Nasdaq symbols to get F and P records for each symbol, summarizing the regular session.

Usually I can successfully drop and add these 25 or 50 at a time, with some interbatch delays.

However, today things went badly with this process. Some symbols didn't return data, and others returned double F and P records. The only way I could get clean EOD summaries was to add and drop one symbol at a time.

Note: In other processes, history requests in 24 simultaneous threads did work as usual.

This may be an unintended side-effect of the upgrade to the new servers. We have found that when we request watches of streaming data from the new server farm, we now see multiple F and P records for each symbol at the start of its session.

You may want to compare results for the 148 and 156 farms.
