Subject Excessive allocation during hinted handoff
Date Wed, 11 May 2011 18:55:20 GMT
Greetings,

I'm experiencing some issues with 2 nodes (out of more than 10). Right
after startup (Listening for thrift clients...) the nodes will create
objects at high rate using all available CPU cores:

 INFO 18:13:15,350 GC for PS Scavenge: 292 ms, 494902976 reclaimed
leaving 2024909864 used; max is 6658457600
 INFO 18:13:20,393 GC for PS Scavenge: 252 ms, 478691280 reclaimed
leaving 2184252600 used; max is 6658457600
....
 INFO 18:15:23,909 GC for PS Scavenge: 283 ms, 452943472 reclaimed
leaving 5523891120 used; max is 6658457600
 INFO 18:15:24,912 GC for PS Scavenge: 273 ms, 466157568 reclaimed
leaving 5594606128 used; max is 6658457600

This will eventually trigger old-gen GC and then the process repeats
until hinted handoff finishes.

The build version was updated from 0.7.2 to 0.7.5 but the behavior was
exactly the same.

Thank you.
