-hc points to script#9 below. script (_, _, affid) (Custom (JoinedTable 0)) = do {-# SCC "script#8" #-}push "takeEmptySeat" $ {-# SCC "script#9" #-}takeEmptySeat Holdem affid [] {-# SCC "script#10" #-}return $ Eat $ Just Go What takeEmptySeat does it call pickTable takeEmptySeat game_type _ filters Go = do push "pickTable" $ pickTable game_type filters return $ Eat $ Just Go pickTable retrieves the list of SrvServerInfo structures, etc. Overall, -hc does not help me figure out where my data is being retained. My understanding is that I need to do -hbdrag,void fo rthat. I did not try -hd and -hy, they would only help me narrow down the producers, right? My program seems to spend 70% of the time collecting garbage. Notice the HUGE overall allocations. This is my trying to launch 4k bots over 8 hours. Only 1k bots were launched and just 300 of those got to play. Maybe because they did not have time with all the garbage collection :-). The tests that I ran previously did not involve heavy network traffic, just a few very small packets. This is why I was able to get to thousands of bots in just a couple of hours and keep them there. ./randomplay +RTS -k3k -P -hc -srandomplay.gc 95,739,560,464 bytes allocated in the heap 887,633,330,904 bytes copied during GC 131,849,008 bytes maximum residency (8730 sample(s)) 330325 collections in generation 0 (557.40s) 8730 collections in generation 1 (16370.05s) 248 Mb total memory in use INIT time 0.00s ( 0.03s elapsed) MUT time 783.40s (1872.75s elapsed) GC time 16927.45s (20075.68s elapsed) RP time 0.00s ( 0.00s elapsed) PROF time 6003.62s (7058.40s elapsed) EXIT time 0.00s ( 0.00s elapsed) Total time 23714.47s (29006.86s elapsed) %GC time 71.4% (69.2% elapsed) <---- isn't this aweful?

What does ordinary heap profiling (-hc, -hd, -hy) tell you about what's in the heap? These options should work fine with STM.
