The procedure to increase the memory for a Muse server installed as a service under Windows is: a) Stop the service by typing at the command prompt: – net stop “Muse Proxy Service” (for Muse Proxy) and/or – net stop “Muse ICE Server” (for Muse ICE) and/or – net stop “Muse HTTP Server” (for Muse HTTP) or net stop “Embedded Apache Tomcat” (for Apache Tomcat) or by navigating to Control Panel -> Administrative Tools -> Services and stop whatever is needed. b) Uninstall the service(s) using the provided script(s): – “UnInstallMuseProxyService.bat” (available in the %MUSE_HOME%\proxy folder) and/or – “UnInstallICEService.bat” (available in the %MUSE_HOME%\use\ice folder)and/or – “UnInstallHTTPService.bat” (available in the %MUSE_HOME%\http folder – if using Muse HTTP Server) or “service.bat remove” (available in the %MUSE_HOME%\tomcat\bin folder – if using Apache Tomcat server) c1) For Muse before 2500, modify the corresponding “JavaService.jvm” file(s) available in the location(s) above mentioned by changing the following lines (using a text editor): – Xms64M – Xmx256M to whatever memory amount needed. Please consider the available physical memory of the machine (). c2) If using Apache Tomcat HTTP server (Muse 2500 or newer), all changes described above still hold, except for the Apache Tomcat – the changes must be made in the %MUSE_HOME%\tomcat\bin\configure.bat file, by modifying the TOMCAT_XMS and/or TOMCAT_XMX values. d) Re-install the service(s) using the provided script(s): – “InstallMuseProxyService.bat” (available in the %MUSE_HOME%\proxy folder) and/or – “InstallICEService.bat” (available in the %MUSE_HOME%\use\ice folder) and/or – “InstallHTTPService.bat” (available in the %MUSE_HOME%\http folder – if using Muse HTTP Server) or “service.bat install” (available in the %MUSE_HOME%\tomcat\bin folder – if using Apache Tomcat server) e) Start the service(s) by typing at the command prompt: – net start “Muse Proxy Service” (for Muse Proxy) and/or – net start “Muse ICE Server” (for Muse ICE) and/or – net start “Muse HTTP Server” (for Muse HTTP) or net start “Embedded Apache Tomcat” (for Apache Tomcat) or by navigating to Control Panel -> Administrative Tools -> Services and start whatever is needed. Note: when editing “JavaService.jvm” like files, one must be aware that each line of the file must end with a “space” and “ENTER” and the last line of it must not have either the “space” nor the “ENTER”.

This may be due to the default Windows limitations for network connections, more exactly the max limit set on simultaneous network connections. Receiving the TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts error in Windows Event Viewer for Event ID 4226 is a clear sign of reaching the limit set on simultaneous network connections.
To disable the TCP connections limit follow the steps:
1) Click Start, type regedit in the Start Search box, and then click regedit.exe in the Programs list. If you are prompted for an administrator password or for confirmation, type your password, or click Continue.
2) Locate and then double-click the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\EnableConnectionRateLimiting
3) In the Value data box, type 0, and then click OK.
4) Exit Registry Editor.
5) Restart the computer.

If the EnableConnectionRateLimiting registry entry does not exist it must be added.

The Microsoft Knowledge Base article KB969710 confirms that the half-open TCP connections limit is disabled in Windows Server 2008 with Service Pack 2 (SP2) and in Windows Vista with Service Pack 2 (SP2).
