Error occurred during initialization of VM Too small initial heap

[Timothy Harris]

I changed the values to 512 and 1024 respectively. 

JVM_MINIMUM_MEMORY="368"
JVM_MAXIMUM_MEMORY="768"

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

Inactive(anon): 668 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 - ./start-jira.sh -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

[Timothy Harris]

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?

[Nic Brough -Adaptavist-]

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

[Timothy Harris]

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

Thank you @Nic Brough -Adaptavist- 

These assignments worked:

JVM_MINIMUM_MEMORY="2048m"
JVM_MAXIMUM_MEMORY="4096m"

These did not :

JVM_MINIMUM_MEMORY="2048"
JVM_MAXIMUM_MEMORY="4096"
