Hi,
i don't know, if it's my stupid configuration or the freeradius, that produces following:

i have two virtual machines (both suse linux 10). on one machine, the freeradius-server is running, on the other machine, i have my little perl-script, that uses rad_eap_test.

perl-script:
---------------------
#!/usr/bin/perl

$i = 0;

while ($i<=50000) {
$i++;
&radtest;
}

sub radtest {
$radiustest = `rad_eap_test -H ******* -P 1812 -S testing123 -u sl90001 -m IEEE8021X -e TLS -j /etc/raddb/certs/sl90001_chain.pem -k /etc/raddb/certs/host_sl90001_chain.pem -a /tmp/rootcerts.pem`;
print $radiustest;
}
------------------

if i run the script only one-time, the state-variable looks something like this:

State = 0x066227990f682a3467daaa2d38adf01c


If i run the script 3 or 4 times at the same time on my virtual-server, the freeradius-server gets some problems... after some time, the server produces such state-variables:
example:
State = 0x0000000000010d000000000000000000

Then, the server switches back to "normal" state-variables...
example:
State = 0x0000000003040db7c026e2b769757300

and then back to:
State = 0x0000000004050d000000000000000000

if the complete debug is helpful, alan, i can send it to you...

is there anything, i can try to test?

Sebastian
