Hi, I have configuring a new FreeRadius 3.0.6 on Centos7 and MariaDB. Is has been working ok (had to increase max connextion and other values) but now I'm getting the radius down every time. MariaDB has radacct with over 10.000.000 rows. I'm connecting 10.000 PPTP users authentication with this Radius, Interim every 30seconds and client-pptp-session 10minutes, but after start mariadb and freeradius exits with this message: [root@rad ~]# systemctl status radiusd radiusd.service - FreeRADIUS high performance RADIUS server. Loaded: loaded (/usr/lib/systemd/system/radiusd.service; disabled) Active: failed (Result: signal) since mar 2015-10-27 22:41:14 CET; 17min ago Process: 12086 ExecStart=/usr/sbin/radiusd -d /etc/raddb (code=exited, status=0/SUCCESS) Process: 12083 ExecStartPre=/usr/sbin/radiusd -C (code=exited, status=0/SUCCESS) Process: 12080 ExecStartPre=/bin/chown -R radiusd.radiusd /var/run/radiusd (code=exited, status=0/SUCCESS) Main PID: 12090 (code=killed, signal=ABRT) CGroup: /system.slice/radiusd.service oct 27 22:36:16 rad.aaa.com systemd[1]: Starting FreeRADIUS high performance RADIUS server.... oct 27 22:36:17 rad.aaa.com systemd[1]: Started FreeRADIUS high performance RADIUS server.. oct 27 22:41:14 rad.aaa.com systemd[1]: radiusd.service: main process exited, code=killed, status=6/ABRT oct 27 22:41:14 rad.aaa.com systemd[1]: Unit radiusd.service entered failed state.
