Hello,I'm experiencing an infinitely growth of memory footprint of freeradius process in our production environment (of course, in our test env. everything goes right).
Clients : - ~60 Alcatel omnistack OS6200 switches doing MAC Authentication (via EAP-MD5), - a few WiFi AP doing either EAP-TLS or EAP-PEAP. - Average load : 5 auth/minute On my first environment production I used : - Server : CentOS 5.6 32 bits on VM, 2 CPUs, 512 Mb RAM - freeradius2 2.1.10-1 i686 packages - MySQL on a different CentOS 5.6 server used for NAS, postauth, checks, etc. process get killed by kernel in less than 48 hours. As it was not the latest freeradius release, I recently moved to : - Server : Debian 4 32 bits on VM, 2 CPUs, 256 Mb RAM- freeradius 2.2.0 downloaded directly, and packaged on the debian server using this wiki page : http://wiki.freeradius.org/building/Build#Building-Debian-packages
process get killed by kernel in less than 36 hours.As I cannot reproduce this on my test environment by using eapol_test, I suspect alcatel frames to trigger a kind of memory leak in freeradius.
I collected different things : - pcap of eap-md5 exchange between freeradius and a switch - valgrind log on my production server - pidstat showing memory usage of freeradius process For now, i'm running out of new ideas to fix this issue...
