When running a tag task through the workflow, or tagging a file from the file menu, we receive this error "the Interwoven web Daemon was unable to contact the Interwoven Servlet Engine. The Interowven Servlet Engine may be down, or running on an unexpect host or port. Please contact your system adminstrator.".
I see this error in error.log - proxy: error reading from remote server returned by /iw-cc/tag, referer:
http://[ts_server]/iw-bin/iw_cgi_wrapper.cgi/iwmetadaata.cgi.
This was just working and no new code has been installed.
I have tried iwreset -a, iwreset -ui, iw.server stop | start, iwaccess stop | start.
