DTN IQFeed, DTN.IQ, DTN ProphetX Support Forums

Hi there,
I'm using the latest version of your client and in the past couple of days I've started seeing problems in the morning with frequent reconnections. For example last night I started the IQFeed client some time after midnight Eastern time. At 7:30am ET my code subscribed to about 1800 US stocks. What followed is hundreds of cycles of disconnection/reconnection over the next 3 hours (and no quotes received during that time for most stocks) after which it seems everything became normal.

This is what I see (repeatedly) in the IQFeed log:
...

On my side of the code I get SERVER DISCONNECTED messages periodically. Furthermore, my code has the logic that if it doesn't receive any quotes for a stock within 40 secs, it unsubscribes and resubscribes. It looks like my code did a total of 300,000 subscription requests this morning as it just wasn't getting any prices.

Thoughts? Does this look like some kind of race condition caused by my repeated unsubscriptions/subscriptions? Giving your API 40 secs to return data for 1800 securities doesn't sound that aggressive to me.

Thanks
