Hello Everybody,
Image

I work with the latest JForex-SDK in Eclipse. I can connect easily ( the last week i had to download the latest JForex-SDK to continue to connect ).
I just use the sample in JForex-SDK with a tiny java class which connect with JNI my previous code in C++. The C++ code just write in a file ask and bid tick.

The use of the cpu should be very very light. It is the way at the beginning.
And after several minutes, the JForex-SDK application ( with my JNI c++ called ) in Eclipse overload the 2 cpu of my computer.
I joined 2 screen copy with :
- the task manager,
- the console of eclipse with a lot of message
Strategy thread queue overloaded with tasks. Ticks in queue - 3, bars - 41510, other tasks - 11367
Strategy thread queue overloaded with tasks. Ticks in queue - 3, bars - 41811, other tasks - 11444
Strategy thread queue overloaded with tasks. Ticks in queue - 3, bars - 41524, other tasks - 11367
Strategy thread queue overloaded with tasks. Ticks in queue - 3, bars - 41811, other tasks - 11444
.......
12 hours later, the application is still running with a big memory. And the cpu is still overloaded....
Sometimes, the application stopped before.

Are there any options i forgot ? or other solutions ? any light in the night ?

Best Regards,

Jeannot

Please give code example that would reproduce the problem.

Hello,
than'k's for your help.
i want to isolate the trouble so i write a new Strategy which :
- is the only one,
- receives all the datafeed for the chosen currencies,
- writes in different files.
It works fine. I joined the MA_Play2.java.

My C++ was called with JNI by my tiny application JForex. I use MinGW under WinXP because Cygwin is incompatible with JNI because posix layer.....
I scan the run of my dll with Dr Memory. It detects "Probable Errors" in ACE and Xerces librairies ( i need these libraries for socket ( ACE ) and XML ( Xerces ) ), not in my code.
Perhaps the management of the heap by the JVM was more sensitive and so the application crashes.
I stopped the JNI solution.

I'm writing a socket server plugged in my JForex Application to communicate with a C++ standalone application.

Bye

Jeannot

PS : when i launch my new tiny application, sometimes there are small error but the apllication is still running.
