When trying to create a memory dump, I am receiving an error: Disk free space is too low, destination folder: /opt/dynatrace/oneagent/log/memorydump/20181024132657_127425. I've checked the available storage on /opt, and it is 5.31GB. Should this be enough storage space for the memory dump? If not, how much space is required?
We are experiencing the same or a similar issue where we have more than sufficient disk on a container and host and the memory dump fails for .NET core application process. We end up with a "summary.json" file on the directory path:
"status": "DotNetHeapDumpController::createMemoryDump failed: 'IllegalStateException: Not enough free disk space (1108017152bytes available \/ 1366358528bytes needed) for memory dump at ..\/..\/..\/..\/..\/..\/..\/native\/special\/dotnet\/libdotnetagent\/src\/main\/cpp\/technology\/dotnet\/DotNetHeapDumpController.cpp:64 at void technology::dotnet::checkAvailableDiskSpace(const agent::Agent&, const string&)'",
Has anyone found out anything else related to disk space issues with memory dumps?
