1 When the `search` plugin is enabled, with the options:
5 # path to the omega cgi program
6 omega_cgi: /usr/lib/cgi-bin/omega/omega
7 # use google site search rather than internal xapian index?
11 Then we see the following error when editing a page from the web browser UI or running `ikiwiki --rebuild`:
14 Error: Exception: Db block overwritten - are there multiple writers?
17 The issue goes away when we disable the 'search' plugin.
19 We're running ikiwiki version 3.20180228-1.
22 > I used to see an error (this one, I think) intermittently on OS X, on incremental rebuilds only.
23 > Haven't seen it in a while, though.
24 > Maybe something got fixed upstream.
25 > What OS, and what version of Xapian and Omega?
27 > Maybe worth blowing away `.ikiwiki/xapian/`, as described in [[tips/inside_dot_ikiwiki]]?
