Windows：重新安装期间CouchDB崩溃

Question

I have a CouchDB installed on a windows machine sometime ago which is working fine and the version was 1.1.0. Now (after few months of first installation) I tried uninstalling the existing CouchDB 1.1.0 and which went successfully but has left the folders '/etc' and '/var' in the installation directory. Now I am trying to re-install using setup-couchdb-1.2.0_otp_R15B.exe without deleting the above folders. After re-install when I am trying to connect to the DB I get the below error in the log. Please help on what could be the issue...

Answer 1

It looks that you'd hit COUCHDB-1482 issue. Try to install more recent CouchDB release (or 1.2.2 if you'd like to stay on 1.2.x branch) that has snappy issue fixed.

Also, try to make clear CouchDB install: move your etc and var dirs somewhere, uninstall CouchDB and remove remain files, install CouchDB and move your var data back. Instead of moving old etc on top of new one, you have to backport your config changes from local.ini file manually (don't override default.ini file!) to be sure that there wouldn't be any config collisions.
