Realtime TimeSales fails for > 300

[enigmatrading]

I am streaming realtime TimeSales data for ~300 stocks simultaneously. After running the program for ~10-15 minutes, calls to the ActiveX API fails and the eSignal application freezes.

I need stream this data continuously for the entire day and thus cannot release any handles for 6.5 hours.

I see this problem on WinXP, eSignal 7.4 (Build 608) and eSignal 7.5 (build 621).

Is this a known limitation in the product? Is there a work around?

Thanks.
