Heap dumps show the data present in memory at the time the dump was generated. A heap dump contains data from a single node.
If you encounter memory issues, a heap dump may provide Infogix Customer Support with useful information to solve the problem. You can generate a heap dump on demand on a node by node basis. The system performs a heap dump automatically for an out-of-memory condition.
Because heap dumps can be quite large and may contain sensitive data, these are not included when you create a diagnostic package.
