I have been experiencing crashes as well under high accounting load (Solaris 7 , mysql accounting). It appears that the use of non thread-safe library functions are responsible for this. I have replaced all the localtime() and ctime() calls with their POSIX thread safe counterparts (localtime_r() and ctime_r()) and radiusd has been running perfectly for the last 2 hours under constant heavy load from radclient (1000+ req/sec) whereas before it would crash within a few minutes.
There are a few other instances of non thread-safe library functions in the source (gmtime, rand and strtok), but they are used mainly at startup so they should not affect the stability, although to be correct, I think they should be replaced with the *_r versions as well. I don't know how applicable these changes are to other OS's (Linux), but perhaps someone running FR on linux could try this and see if it helps. Eddie - List info/subscribe/unsubscribe?
