I haven't logged a bug because I haven't yet figured out the steps to exactly reproduce this, but I've been seeing something strange since I've started using 2.3.1.
I have a thread pool in my application which gets assigned to run a "job" by the user, does so, and then waits until it's called on again to run another job. Since 2.3.1 gives a different heap to each thread, I've added debugging code to periodically log the heap status returned by GetFPCHeapStatus. At first, everything starts out fine: 0xB0A93BB0 heap status: cu=1456, cs=786432, cf=784976, mu=30720, ms=1048576 0xB0691BB0 heap status: cu=1456, cs=786432, cf=784976, mu=14080, ms=1048576 0xAFE85BB0 heap status: cu=1456, cs=786432, cf=784976, mu=30720, ms=1048576 Notice that "current size" minus "current free" equals "current used", just like you'd expect. After running for a few hours though, look at my numbers: 0xB0287BB0 heap status: cu=4294952816, cs=786432, cf=800912, mu=4294967280, ms=5144576 0xAFA83BB0 heap status: cu=4294873136, cs=1146880, cf=1241040, mu=4294967280, ms=5603328 0xB22C1BB0 heap status: cu=4294950256, cs=950272, cf=967312, mu=4294967280, ms=5570560 0xB26CABB0 heap status: cu=4294956896, cs=983040, cf=993440, mu=4294967280, ms=5570560 0xAF681BB0 heap status: cu=4294885088, cs=917504, cf=999712, mu=4294967280, ms=5603328 0xAF27FBB0 heap status: cu=4294844176, cs=1179648, cf=1302768, mu=4294967280, ms=5603328 0xB1EADBB0 heap status: cu=4294963824, cs=950272, cf=953744, mu=4294967280, ms=5570560 0xB3EE6BB0 heap status: cu=4294956896, cs=950272, cf=960672, mu=4294967280, ms=5570560 One by one, over time, the "current free" becomes *greater* than the "current size", so the calculations are all screwy (current used is negative, etc.). Does anyone know about changes to this which could cause this problem? It's rather annoying... I know the each heap isn't really using 4.2 gigabytes, but I wish the numbers were accurate. -SG -- This email is fiction.
