Event Details

Product: Windows Subsystem for UNIX-based Applications
ID: 2018
Source: Microsoft-Windows-SUA-Psxrun
Version: 6.0
Symbolic Name: ERR_NO_MEMORY
Message: Out of Memory

Free some memory

An error occurred during memory allocation. This can happen if the Windows server is running low on virtual memory. Try closing some applications that are not required and are using virtual memory, and then try running the Subsystem for UNIX-based Applications application again. If this does not correct the problem, try restarting the computer to clear the error.


Because multiple instances of Psxrun can be running at once, it is best to verify Psxrun in Windows Task Manager not by checking on a particular instance of Psxrun, but by verifying that the specific POSIX process or application launched by using Psxrun is running.

To verify that Psxrun is running:

  1. Open Windows Task Manager by pressing CTRL+ALT+DEL, and then clicking Start Task Manager.
  2. On the Processes tab, select the Show processes from all users check box.
  3. Verify that a specific POSIX process you have started by using Subsystem for UNIX-based Applications is running.

If the POSIX application or process that has been launched by using Psxrun is indicated as running in Task Manager, then Psxrun is fully available. If the process is not running, critical errors are preventing Psxrun from being available.
