GC (Allocation Failure)

[Shinesun]

Hi, guys,

Found the following in almost every Druid's node logs:

182.887: [GC (Allocation Failure) 182.887: [ParNew: 310335K->11198K(314560K), 0.1996490 secs] 310335K->23938K(1013632K), 0.1997860 secs] [Times: user=0.93 sys=0.11, real=0.20 secs]

Can you please provide more details on this because couldn't find such? Is this something to worry about/need to be resolved?

Regards,
Shinesun

Hi Shinesun,

This is just Java logging that it ran out of heap space and it triggered a garbage collection.  It is completely normal as long as it doesn't happen too frequently, or take too long to run.
