Out of memory - Machine
In this document, we will use the information from the actual root cause analysis to make a generic view that can be used if you run into the same or a similar problem in the future. Finally, the document will describe the situation, the problem, the analysis, and the result.
Should you have any questions, please get in touch with academy@emagiz.com.
1. Situation
An error is received saying that the application memory is above the treshold.
2. Problem
The problem in this case was overcommitted memory. E.g. the processes on the machine together take up too much memory preventing the machine to perform well.
3. Analysis
3.1 Reproduction
N/A
3.2 Analysis
The error led us to investigate the memory settings of the machine. It is seen that the memory configuration is in total slightly less than the maximum. However, the JMS heap can be upped in some cases in which extra memory is needed. In those cases the total memory will rise above the maximum.
4. Result
The memory settings of a machine should be configured such that there is space for allocation extra memory.
