The Dump Heap option within the Admin Console allows administrators to request that the server write the contents of its memory to a file on disk, which can later be analyzed. This can be useful to determine what is consuming memory in cases where the LabKey Server process is running out of memory, typically by LabKey staff. Note that this can be quite large - often gigabytes in size.

Upon completion of writing the file, the resulting page will give the user the path to the file, which will be under the LABKEY_HOME directory.

For more information, and alternative ways to request a heap dump in cases where the web user interface is unresponsive, see Dump Memory and Thread Usage Debugging Information.
