I've got a client's server running FreeRADIUS 2.1.10 from source. Linux
kernel 2.6.35.7, heavily customized Slackware 13.0 So far, not using
chroot, running as root.
It's a EAP-TLS setup with OpenSSL verifying via 'client = ',
tmpdir = /tmp/radiusd
Everything has been fine for weeks, but this morning:
Jan 3 08:04:32 dns1 radiusd[22737]: Invalid user: [xxxxxx/<no User-Password
attribute>] (from client xxxx port 0 cli xx-xx-xx-xx-xx-xx)
Jan 3 08:04:36 dns1 radiusd[22737]: [auth_log] rlm_detail: Couldn't open file
/var/log/radius/radacct/x.x.x.x/auth-detail-20110103: Too many open files
I checked 'lsof -p' against the running radiusd and the line count of it's
output was 1054. Other than the typical linked libraries, socket, etc. at
the top, the rest was "(deleted)" lines like this one:
radiusd 22737 root 1022u REG 104,2 1334 404429
/tmp/radiusd/radiusd.client.XXGcdadx (deleted)
In the meantime, I raised the limit with ulimit and restarted.
I'm open to further (late night) testing, patching, whatever...
Thanks,
Jason
