# Error - Domino HTTP Error Loading Java Virtual Machine

## **Problem**

Domino HTTP fails to load Java Virtual Machine. As result, the HTTP task fails to start.

## **Cause**

Conflict with Java heap size settings in notes.ini file prevented the Java Virtual Machine (JVM) from loading.

## Diagnosing the problem

Domino Server console reported following messages:

`03/29/2011 08:39:58 AM HTTP JVM: JVMJ9GC019E -Xms too large for -Xmx`\
 `03/29/2011 08:39:58 AM HTTP JVM: JVMJ9VM015W Initialization error for library j9gc24(2): Failed to initialize`\
 `03/29/2011 08:39:58 AM JVM: The Java Virtual Machine creation returned an invalid JVM machine pointer.`\
 `03/29/2011 08:39:58 AM JVM: Java Virtual Machine failed to start`\
 `03/29/2011 08:39:58 AM HTTP Server: Error Loading Java Virtual Machine`\
 `03/29/2011 08:39:58 AM HTTP Server: JVM: Missing entrypoint in JVM runtime library.`\
 `03/29/2011 08:39:58 AM HTTP Server: Shutdown`

 Message "-Xms too large for -Xmx" indicates that the initial Java heap size is larger than the maximum Java heap size.

 In one case, the Notes.ini file had the following parameters:

 `HTTPJVMMaxHeapSize=64M`\
`HTTPJVMMaxHeapSizeSet=1`\
`JavaMaxHeapSize=268435456`\
`JavaMinHeapSize=134217728`

 The JavaMinHeapSize of 128MB is set higher than the HTTP's JVM heap size 64MB.

## **Resolving the problem**

The solution is to remove or lower JavaMinHeapSize (JavaMinHeapSize=67108864) or alternatively, increase HTTPJVMMaxHeapSize to 128M (HTTPJVMMaxHeapSize=128M).<br>
