Memory Usage on Linux server

Hi Jay

Monitoring the memory usage of BW processes is not so easy as they are Java processes. Top doesn't show the sum of native memory and heap used by the Java processes. From the administrator you can check the heap used by each process, while the native usually doesn't change very much. If you can modify the deployment configuration I suggest you to enable the jconsole and use it to monitor the processes.

In any case the drop in the memory usage is strange. But many things could have happened:
1) Another process was taking a lot of memory, but Top didn't show it (still a heap and native memory issue)
2) Actually something is not working. From the administrator you can check the activity of the BW processes
3) Simply someone modified the configuration of the virtual machine adding some memory (the left hand doesn't know ... happens often)
