| Defect/Enhancement Number | |
| Cause | pmap output indicates total 4063568K of memory allocated in the JVM with: 00030000 589696K rwx-- [ heap ] // that's the native heap 2E400000 1228800K rw--- // these three are the Java heap 79400000 1916928K rw--- // EE400000 131072K rw--- // pstack output indicates that the crash is caused by febd098c memcpy (0, 23299ea0, 0, 4000, ff2303d8, 0) 584 The crash occurs due to exhaustion of the _native_ heap, most likely due to the Java heap that's too large. |
| Resolution | Ensure the application is being profiled, the memory consumption analyzed, and the corresponding code is investigated for any memory leaks. |
| Workaround | |
| Notes | Should the Artix container crash, ensure you collect pstack/pmap analysis files and provide these to Micro Focus Technical Support. |
