Thank you for giving a good starting point for the investigation.

Please check the folloing things:

- Are there two instances of dispatcher running, one with --osm-base and 
the other with --areas? They are both necessary.

- Is there a file entry for 
/home/osm-3s_v0.7.53/bin/db/osm3s_v0.7.53_areas ?

It should look like this:
srw-rw-rw- 1 roland roland      0 Apr 25 06:10 osm3s_v0.7.53_areas

i.e., have a "s" in front to show that it is a socket, and "rw" for 
everybody. You can compare it to

srw-rw-rw- 1 roland roland      0 Apr 25 06:10 osm3s_v0.7.53_osm_base

on your system.

- Please check whether there is any system like SELinux or AppArmor 
active and whether it has a message in the logs.

Some background: I've seen this situation the first time, and probably 
nobody else has before. The error messages show the third token (here: 
"Unix_Socket::7") to identify the unique location in source code where 
the error happened. In this case, it is on the system call "connect".

Error 111 is most likely EACCES, although the message text "Connection 
refused" is rather confusing. It is a PITA that the operatins system 
messages do not line up with the values explained in the operating 
system's man pages.

This points to either one of the directories not being readable. We can 
rule out that because the standard request works. This is where I have 
to probe on the file rights whether the access is denied by Unix file 
rights or by some invisible component.

Best regards,

Roland
