Description Arpan Jindal 2005-09-26 00:39:29 UTC
hi all

i had just installed gentoo. i am not able to set a java heap size of
more than 2600m on these machines. I m getting following error
--------------------------------------------------
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.
--------------------------------------------------

My suspicion is this is a kernel tunable issue, because i have never faced this
issue in fedora stock kernels.

so what might be the problem and i have tries all the latest java software like
jdk1.5.0

but same thing is running fine in in fedora with rany amount of ram like 1gb, 2
gb and 1 gb swap but same thing is not even working in Gentoo with 4gb ram and 1
gb swap

so plz help me out

Make sure you have large memory support in your kernel.

# CONFIG_NOHIGHMEM is not set
CONFIG_HIGHMEM4G=y
# CONFIG_HIGHMEM64G is not set
CONFIG_HIGHMEM=y

That is mine, you should compare ( and probably change ) yours.

Please can you attach emerge --info, output of free -m and your .config ?
