Hi
Where (or how) can I find the default Xmx size?
If I try a -Xmx400m I get the same error, so I'm thinking the default
max size could be greater than my free RAM + SWAP.
In this moment:
linux:~ # free -m
total used free shared buffers cached
Mem: 503 495 7 0 63 183
-/+ buffers/cache: 248 254
Swap: 127 0 127
linux:~ #
254 + 127= 381 mega
Now I can create a java virtual machine with at max -Xmx390m.
So I'd much helped on knowing what is the default xmx value - googling
it does not help: I found only:
http://www.nabble.com/changeset-in--hg-icedtea:-*-patches-icedtea-cacao-Compiler-gcc-g...-td14884869.html
Please if you're aware of a more suitable mailing list, tell me it.
Best regards
Roberto
