memory corruption when proxying accounting requests

[Jørn Kostøl]

Hi, 

 

I’m having problems proxying accounting requests on FreeRadius 2. 

 

Local auth and acct works fine, and proxying auth works. But as soon as I
try to proxy accounting then Freeradius crashes. 

I have tried proxying to an old stable freeradius server, through a home
server, direct to a virtual server, home server pools, and I have tried to
add and remove all the modules and options I can to try to find if there is
a particular part that makes it crash but no luck. 

 

The accounting requests gets sent, and FreeRadius crashes after. 

 

I’ve tried to install both version FreeRadius 2.0.0 and 2.0.1 on two
different servers both running different Ubuntu versions. 

 

Anyone have an idea what I can try next?

 

Here is output from one of the installations:
