Two applications are attempting to DELETE a piece of content at or near the same time. Normally the first gets a 204 No Content, and the second gets a 404 Not Found. (see 2569 below). Occasionally the second gets a 403 Forbidden and an error is generated.(see 1866 below) An example for the access log 10.0.0.203 - - [19/Feb/2017:00:13:13 +0000] "DELETE /perm/A/2569 HTTP/1.1" 204 - "-" "-" 10.0.0.201 - - [19/Feb/2017:00:13:13 +0000] "DELETE /perm/A/2569 HTTP/1.1" 404 209 "-" "-" 10.0.1.202 - - [19/Feb/2017:00:13:13 +0000] "DELETE /perm/A/1866 HTTP/1.1" 204 - "-" "-" 10.0.1.203 - - [19/Feb/2017:00:13:13 +0000] "DELETE /perm/A/1866 HTTP/1.1" 403 213 "-" "-" Then the error log [Sun Feb 19 00:13:13.989597 2017] [dav:error] [pid 31097] [client 10.0.1.203:35970] Could not DELETE /perm/A/1866. [403, #0] I'd expect the behavior to be consistent like the first case. Thoughts?
