Hi,

What does this warning mean?  
[2012-08-17 15:26:56,997][WARN][monitor.jvm] [es2]  
[gc][ParNew][5][2] duration [1s], collections [1]/[1.1s], total  
[1s]/[1.1s], memory [198.3mb]-\>[131mb]/[7.9gb], all\_pools {[Code Cache]  
[1.2mb]-\>[1.2mb]/[48mb]}{[Par Eden Space]  
[175.3mb]-\>[6.5mb]/[266.2mb]}{[Par Survivor Space]  
[22.9mb]-\>[33.2mb]/[33.2mb]}{[CMS Old Gen] [0b]-\>[91.1mb]/[7.6gb]}{[CMS  
Perm Gen] [21.9mb]-\>[21.9mb]/[82mb]}

I am not sure if this is not the reason of 100% processor usage.

Thank you for help.

Best regards.  
Marcin Dojwa.
