Out of memory error

Hello,
while executing just a single “keyword search” ingest, I have got this error message:
“this writer hit an outofmemory error; cannot commit”.
I got this error for each evidences in my case.

My autopsy has a maximum JVM memory of 16GB, and runs on a i7 intel processor.

Is the keyword searching completed at all, or do I have a “partial” indexing of the evidences?

Thank you for your time and consideration.
