The occurrences tended to be spaced weeks apart, and consist of clusters of hangs 4-12 hours apart over a few days. I had formed the hypothesis that a particular client or type of client was triggering it - when they realised they could never authenticate (because unknown to them, they were hanging the server) they went away.
That's unfortunate...
These problems generally manifest in one of two ways:
* the process hangs (and is unkillable except by -9) - most common * the process CPU runs to 100% - less common
Sounds like it's trying to dump core after allocating tons of memory, and getting a SEGV.
The service basically does PEAP/MS-CHAP with ntlm_auth helper and rlm_sql_postgresql; the database does not seem to be the issue. We are not HUPing the server.
Can you give a list of modules you are using?
Does anyone have any thoughts on what I might to do narrow the problem down?
If everyone with this issue can give a list of modules they use, along with which versions work, and which ones don't, that would help. Alan DeKok.
