Hi, I'm in the processing or updating a distribution's v3.6.3 syslog-ng configuration to v3.9.1 and am running into some issues getting syslog-ng started. The first one was: Starting syslog-ng: Error parsing config, Error compiling template (Unknown template function "format-json") in /usr/share/syslog-ng/include/scl/cim/template.conf at line 23, column 32 I found a reference online to fixing this by removing /usr/share/syslog-ng/include/scl/cim and this indeed got me past this error (hopefully this is an otherwise benign modification). I'm now stuck at the following error: Starting syslog-ng: [2017-02-22T08:07:50.101422] Error checking the uniqueness of the persist names, please override it with persist-name option. Shutting down.; persist_name='affile_dd_writers(/var/log/abc/audit_log)', location='/etc/syslog-ng.conf:128:33' Here's snippet from my configuration file that this error message references: ... destination d_abcaudit { file("/var/log/abc/audit_log" template(t_NAFormat)); }; destination d_abcaudit_Prio { file("/var/log/abc/audit_log" template(t_NAFormat_Prio)); }; --> destination d_abcaudit_IPtab { file("/var/log/abc/audit_log" template(t_abcFormat_IPtab)); }; destination d_abcmessage_Prio { file("/dev/null"); }; ... I wasn't able to find any documentation or guidance on the "persist-name" option. Any ideas on how I should go about fixing this error? Thanks, -David
