MT4 Memory error, History Base Error

 

I am fairly new to MT4 and I just recently put my MT4 platform on a virtual server. It ran fine for about 10 hours and now I am getting 2 different memory errors.

The 2 errors are:

2008.12.02 10:11:18 HistoryBase: not enough memory 'EURUSD1' [3447835 bars]
2008.12.02 10:11:36 Memory handler: cannot allocate 151716004 bytes of memory

I have done a couple of things on the server. I checked to make sure that I wasn't over the allocated memory. It appears I was close but not over. I then did a restart of the server and now I am only using about 15% of my allocated memory. I then restarted MT4 and have received the same message. Any ideas? I did do some back testing last night but I have done that before with no side effects.

Thanks,

Jeff
