Hi, We are using syslog-ng-3.4.0alpha2 binary and trying to run the syslog-ng server configuration file, but its not starting the syslog ng server. We are getting the following error incase of f__nonconsole_access filter when we ran the syslog-ng binary in debug mode. Filter rule evaluation result; result='match', rule='f_nonconsole_access', location='/ne_data/conf/syslogng/syslog-ng_server.conf:58:29' ** ERROR:logmsg.c:535:log_msg_set_value_indirect: assertion failed: (!log_msg_is_write_protected(self)) Abort (core dumped) PFA the debug.log The server conf is having the following line for the above mentioned filter, template ltemgr_msg_template { template("$S_ISODATE $HOST $FACILITY_NUM/$LEVEL_NUM $MSG\n"); }; #To strip of the msg_id introduced by syslogd rewrite rw_msg{subst("\\[.*\\]", "", value("MESSAGE"));}; source s_LTEMGR_SYSLOG_CLIENTS{ tcp (ip (27.132.98.69) port(6515) max-connections(4) tls( key_file("/ne_data/conf/certificates/MOCM/MOCM_key.pem") cert_file("/ne_data/conf/certificates/MOCM/MOCM_SB_server.pem") ca_dir("/ne_data/conf/certificates/SYSLOGNG") cipher_suite("ALL:!aNULL:!ADH:!eNULL:!LOW:!EXP:RC4+RSA:+HIGH:+MEDIUM:!SSLv2") peer_verify(optional-untrusted) ) ); }; ....... destination d_ltemgr_nonconsoleaccess_log {file("/ne_data/syslog/ems" perm(0644) template(ltemgr_msg_template)); }; ...... filter f_nonconsole_access { level(info..notice) and facility(auth) and ( match("Accepted password for" value("MESSAGE")) or match("Failed password for" value("MESSAGE")) ); }; ..... log { source(s_LTEMGR_SYSLOG_CLIENTS); filter(f_nonconsole_access); rewrite(rw_msg); destination(d_ltemgr_nonconsoleaccess_log); }; Without debug mode, we were able to run the server but central logging is not happening when tried with logger command.
