I get the following output from running bash -x bin/run_local.sh

+ java -classpath appjet-eth-dev.jar:data:lib/dnsjava-2.0.6.jar:lib/

Error occurred during initialization of VM
Could not reserve enough space for object heap

And running strace -fi I get the following output that seems related:

[pid 20971] [ 335a6d085a] mmap(0x2aaab3910000, 986513408,
PROT_READ|PROT_WRITE|PROT_EXEC, MAP_PRIVATE|MAP_FIXED|MAP_ANONYMOUS,
-1, 0) = -1 ENOMEM (Cannot allocate memory)
[pid 20971] [ 335b20d54b] write(1, "Error occurred during
initializa"..., 43Error occurred during initialization of VM
)

My kernel.shmax is high enough. I don't understand what could be
happening here.

Anyone have any insight?

Centos5.4 btw.

I found the problem elswhere here. Should have searched more.

I am on a slicehost that has up to 4GB of ram, but that changes. I am
only guaranteed 256Mb.

Passing 128m to the startup script got me past that point to a null
pointer exception

Startup execution failed with error.
