Regardless of what actually happened, I'm of the opinion that all exchanges should be using the exact same rules as far as circuit breakers and such when participating in the same market(s). That probably would have prevented much of Thursday's carnage.

Well, one shows you what the application thinks it is using while the other shows you how much memory is allocated by the operating system for the application. Both provide useful information but possibly for different things. Well if you have a 96MB memory pool it's pretty unlikely that it...

Ah, I found the difference. I was using the IB recommended start line: java -cp jts.jar:hsqldb.jar:jcommon-1.0.12.jar:jhall.jar:other.jar:rss.jar -Dsun.java2d.noddraw=true -Xmx512M ibgateway.GWClient . Which reserves 512MB for the memory allocation pool. Of course I'm not sure if it...
