Hi I am using syslog version 2.0.8 and all is running well. I am using it to log a number of Cisco devices. Recently I tried to add an additional number of devices that I would like to have their syslog sent to the Syslog-NG server. This is the syntax used in the config file: destination CAT1 { file("/var/log/switches/CAT1/log.txt" dir_perm(0755) perm(0755));}; filter f_filter73 { netmask(192.168.150.25);}; log { source(s_udp); filter(f_filter73); destination(CAT1); }; However, when I restart syslog-ng I get the following error: Stopping syslog-ng: [OK] Starting syslog-ng: yacc stack overflow at 314 YACC is complaining of a stack overflow. Syslog-ng is running on Fedora Core 8. Did anyone encounter this problem before? Any help would be appreciated.
