Resolve 'WinError: 8 Not enough storage is available to process this command' along with block memory allocation error encountered while running Sagent plan.


While running Sagent plan through sarun, 'WinError: 8 Not enough storage is available to process this command' is encountered. Also, 'Error during block memory allocation. A memory extent cannot be reserved' is present in the SAPPCOM logs.


Possible root causes are:
  • Improper Dataflow server tuning.
  • Not enough disk space on Dataflow server machine.
  • A sudden increase in Data processed.
  • Any recent changes to the environment that are not supported or obsolete.


UPDATED: November 2, 2018

In order to troubleshoot, share the following information with PB Support:
  • Environment details i.e Server type, available physical memory and RAM on the server.
  • Sagent configuration i.e 32-bit or 64-bit?
  • How are plans executed - via sarun command, Automation, or client tools (Design/Information Studio, WebLink)?
  • When did issue start?
  • Is this error message consistent with every plan execution or it intermittent?
  • Is there any sudden increase in data processed?
  • Any recent changes to the environment?
  • The issue occurs for existing plan or newly created plan?
  • What are the results of the restart of the DFS server or reboot of the server machine?
  • Registry export of 'HKLM\SOFTWARE\Sagent'.
In case of any irregularity/issues with the Dataflow server tuning, the 'configuration parameters' are to be changed/set in the Registry settings or the 'Configuration' tab of Sagent Admin.
