Just an idea : Orient could catch OutOfMemoryError on
Unsafe.allocateMemory() and automatically decrease the disk cache size.
These feature would be useful in general (with a warning in logs) and
really necessary when Orient is used in contexts where the system is not
well known and not well administered like a user desktop...

It is not heap exception it is off heap exception, your setting for
disk cache size is bigger than available amount of RAM.
Please decrease it.

Hi Luca,
The JVM had 2.8 GB of heap allocated and it was using about 2.0 GB
at the time the exception occurred.

Following up on my question, there is physical memory
available on the system when the exception is thrown. I am
now suspecting that direct memory needs swap space backing
for it to be allocated, so is the possible lack of swap
space causing the OOM exceptions?

We are working with OrientDB 2.0.1 and after loading a
large number of records, we create indexes and run
into the following exception. Do you have any
suggestions on what we need to tune to get past the
error?
Thanks.
SEVERE: {db=person-db} Exception during index rebuild.
Exception was caused by following key/ value pair -
key Jayden, value #11:104588. Rebuild will continue
from this point.
