Problem

The following appears in the atlassian-bitbucket.log:

 
c.a.j.s.w.c.s.JohnsonHttpRequestHandlerServlet HttpRequestHandlerServlet [scmServlet] cannot be initialised to service an incoming request; redirecting to /unavailable

Problem

To replicate this issue in a test environment at will do the following:

Assumption:

• Have a remote repository defined as Bitbucket Server on your system (or modify the shell scripts below to use an appropriate remote name)
• Clear out all the old logs from $BITBUCKET_HOME/logs
• Bitbucket Server is running on a *nix style OS.  If running on Windows change the shell script to appropriately configured batch files
• Bitbucket Server is running

Create one of the following shell scripts:

for i in {1..150000}
do
  echo Fetching from bitbucket
  git fetch bitbucket
done

or

for i in {1..150000}
do
  echo Pulling from bitbucket
  git pull bitbucket
done

(chmod +x the .sh file to make it executable)

Open two terminal windows to the server.

1. In Terminal Window A (TWA) start the shell script that you created.
2. In Terminal Window B (TWB) stop Bitbucket Server ./stop-bitbucket.sh
3. In TWA note that you will start getting "connection refused" messages
4. In TWB start Bitbucket Server ./start-bitbucket.sh
5. In TWA the connection refused messages will stop and you will start to get errors saying something about "not valid: is this a git repository". Eventually the messages will return to Fetching/Pulling from Bitbucket Server. At this point you can stop the shell script (control-c) and then review the atlassian-bitbucket.log

Cause

These warning messages are a result of git fetch or git pull commands that are being sent to the the Bitbucket Server instance while Bitbucket Server is stopping\starting and is not in a state that it can actually process the requests

Resolution

• These messages in the log can be safely ignored
