Overpass API developpement

[Brian Vogelgesang <>]

I'm really trying every angle to get this working. I tried launching the 
docker image and passing it the database files I have. I get the same error 
when it tries to init the dispatcher

/launch_overpass.sh: line 17:    96 Segmentation fault      (core dumped) 
$BINDIR/dispatcher --osm-base --meta --db-dir=$DBDIR

What is Segment fault trying to communicate in this context?

    I created a new machine with Ubuntu 18.04 and I still receive the segment 
fault when I try to start the dispatcher. Below are the prompts I run to get 
osm3_query setup on my machine. Note that the database files have already 
been downloaded with bin/download_clone.sh to a separate SSD disk that is 
attached to the machine

            We have December 2019. Ubuntu 14.04 has fallen out of maintenance 
for
            some months. Unless you have an important reason to run a five 
year old
            OS, I strongly advise against that.
            
            Other than that: Please check
            - is there a file /dev/shm/osm3s_v0.7.55_osm_base
               and which permissions does it have?
            - is there a file $DB_DIR/osm3s_v0.7.55_osm_base
               and which permissions does it have?
            - What is the content of the file $DB_DIR/transactions.log ?
            
            Best
            Roland
