Error occurred during initialization of VM Too small initial heap

I changed the values to 512 and 1024 respectively. 



Now JIRA will not start. Complains the heap is small. Changed the values back and still won't start with same error message.

cat /proc/meminfo shows:

MemTotal: 8063248 kB
MemFree: 5456820 kB
Buffers: 622272 kB
Cached: 1517056 kB
SwapCached: 804 kB
Active: 1300020 kB
Inactive: 873112 kB
Active(anon): 33136 kB
Inactive(anon): 668 kB
Active(file): 1266884 kB
Inactive(file): 872444 kB
Unevictable: 0 kB
Mlocked: 0 kB
SwapTotal: 2097148 kB
SwapFree: 2083376 kB

So there is enough RAM. What is going on here?

Executing - ./ -fg and I get:

You're allocating the memory in bytes - it needs Megabytes.  Try adding "m" to the end of the numbers to tell it you mean Mb

OK, didn't know that. But how did this work before? The standard values did not have this notation. Does that mean that these values are not initially used?

I don't know where you got those numbers from - I get the "m" on the end when I do a default installation

Maybe I was just blind :-) Anyways thanks for the help!
