SUMMARY
The Interix subsystem which is part of Windows Services For UNIX (SFU) 3.0 has a maximum number of processes that can be run at the same time. You can increase the default number of processes by making a change to a registry value. This article describes how to do so.



MORE INFORMATION
Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

Use Registry Editor to locate the following registry key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Services For Unix

Add the following entry:

Value Name: MaxProc

Value Type: REG_DWORD

Data Range: 100-1000 (The default is 200)

The Interix subsystem provides a POSIX-compliant subsystem that runs UNIX shells, utilities, and programs natively alongside of Windows programs. In addition to the subsystem, over 400 utilities are available, and a complete software development kit to make it easy to port your UNIX programs to run on Interix. This product was previously available as Microsoft Interix.

Note Service for UNIX 3.5 does not have a set limit on the number of active processes. The number of Interix processes on SFU 3.5 is limited by available system resources.
