Cannot Connect To CouchDb On Windows 7 64 Bit Professional

Try 'erl' (or 'werl'?) then 'application:start(os_mon).' excluding single quotes and including the dot, and report what it says.

application:start(sasl). ;)

attached crash dump

we should make os_mon optional (it�s buggy/broken in other situations, like if a mountpoint has a space in the name..)
It exists only for the compaction daemon which is disabled by default, so this is just breaking you for no upside.
B.

any idea why it happens? any way to overcome it? any way to workaround it?
Thanks!!

The error is;
{enoent,  [{erlang,open_port, [{spawn, "c:/PROGRA~2/Apache Software Foundation/CouchDB/lib/os_mon-2.2.7/priv/bin/win32sysinfo.exe"}
Meaning it can�t find that to launch it. Does it exist? Or is ~2 or the spaces confusing erlang?
B.

it is there. no problem to run that command.

Hrm, no clue then. Will need a Windows/Erlang developer.
B.

btw, where does it take the "c:/PROGRA~2" from? can i instruct it to use
another path?
[note that we don't have the issue on many other windows 7 machines with
the exact paths]

I think the "c:/PROGRA~2" may ultimately come from the erl.ini file in the
CouchDb bin directory but I'm not sure of that, and don't know if changing
it there would be sufficient. The "~2" business may not be an error either
- some programs still live in the days of 8.3 file names and use this
convention for reporting names that don't fit that convention.
If you want to try another path, the simplest way would be to uninstall
CouchDb and reinstall somewhere like C:\CouchDb which is short and has no
spaces. While the uninstall should leave your local.ini file and databases
alone, it would be best to back them up somewhere and then copy to the new
installation.

Hrm, no clue  
B.  
I’ve seen this periodically, but never reproduced it locally.
Somehow Windows (or possibly Erlang) is unable to handle this combination of an abbreviated 8.3 mangled path & a full path, even though on a default windows install this works perfectly.
The workaround for impacted boxes is simply to install to a path without spaces, which IMO is always a Good Thing Anyway.
A+

Hi,
The path in erl.ini was just like on my machine where it works fine -
C:\\Program Files (x86)\\Apache Software Foundation\\CouchDB
So I followed the suggestion and installed on C:\ and all works fine :-)
Thanks!
