[04/26] couch commit: updated refs/heads/windsor-merge to 14dc5e9

[rn...@apache.org]

Always report why couch_server crashes

On servers with a large number of open databases the couch_server state
is too large to be logged, and so when it crashes we miss the reason for
the crash.  This patch adds an extra message that redacts enough of the
server state to ensure a properly-formatted message.
