Java Query on RAM Memory
Hi Experts,

I have a linux system , which triggers a alarm if RAM memory goes above 70%... When i see top command i cant find any process utilizing much of memory .. Can anyone tell me what could be the reason for high memory utilization.. Bellow is the free command o/p:

Code:
 free                                                             
             total       used       free     shared    buffers     cached                    
Mem:       3626072    2981104     644968          0     581724    1846152                    
-/+ buffers/cache:     553228    3072844                                                     
Swap:      4194296          0    4194296
