<div class="moz-cite-prefix">Hi Nicolas,<br>
<br>
creating world wide graph needs lots of RAM (normal graph needs
8GB, CH needs 13GB, creating the latter one needs ~22GB). Although
for only belgium territority this should be sufficient. Not sure
how your additional data source looks like and what the exact
reason of the OOM might cause. What is the exact stacktrace?<br>
<br>
Did you increase the default -Xmx1000m settings either by editing
graphhopper.sh or by providing your own JAVA_OPTS? (export
JAVA_OPTS="-Xmx2000m ..."; ./graphhopper.sh ...)<br>
<br>
<span lang="EN-US">> I’d like to know if there could be a way
to flush the DataAccess on a regular basis to release memory.</span><br>
<br>
You could use the MMapDataAccess but you'll have to make this
thread-safe (e.g. with a simple DataAccess wrapper). But if not
enough RAM is available => everything will be slower (import +
queries)<br>
<br>
Regards,<br>
Peter.<br>
