I have an input file for radmin with the following content: debug file /var/log/radius/nw2.log debug condition '(NAS-IP-Address == "172.31.110.147") || (NAS-IP-Address == "172.31.110.149") || (NAS-IP-Address == "149.246.185.169")' When those commands have been executed and some debugging shows up int the logfile, I want to switch to another log. changing the radmin input file to debug file /var/log/radius/nw3.log debug condition '(NAS-IP-Address == "172.31.110.147") || (NAS-IP-Address == "172.31.110.149") || (NAS-IP-Address == "149.246.185.169")' and executing the commands, freeradius in the actual 2.1.1 version dies. This is, what gdb show up: Loaded symbols for /usr/lib64/freeradius/rlm_sql_log.so 0x00002b091e323562 in ?? () from /lib64/libc.so.6 (gdb) cont Continuing. Program received signal SIGABRT, Aborted.
