Thread queue overflow

Hi,

A thread queue overflow error occurs in my strategy:
"Thread queue overflow. Ticks in queue - 0, bars - 500, other tasks - 0, ThreadPoolExecutor state - false Strategy thread in [java.net.PlainSocketImpl.socketConnect(Native Method)]"

In this trategy, onTick is empty (no code), onBar saves (writes file) bars of 20 pairs every 10 secs. The strategy does nothing else.

How to avoid this error ?

It seems to occur:
- since new version of JForex
- when internet connection speed goes down

Thanks

Hi,
this could happen if you change a system time on your PC.
In a next JForex version, there won't be the queue size restriction.

This problem started to appear on DEMO accounts. The reason is increased amount of currency pairs. We will fix this problem in next version, but for now you can unsubscribe from currency pairs that you don't use
