We're seeing bursts of:
Thu Oct 10 11:52:14 2013 : Info: WARNING: Child is hung for request
47516341 in component authenticate module peap.
Thu Oct 10 11:52:16 2013 : Info: WARNING: Module rlm_eap became
unblocked for request 47516341
...since the return of our students this year.
I am 99% sure this is ntlm_auth being slow, and I have a strong
suspicion this is related to some changes in our AD infrastructure over
In order to prove this to the AD team, I need to gather some timing
stats for ntlm_auth; can anyone think of an easy way to do this within
AFAIK there aren't any xlat that back onto gettimeofday; the various
request time attribute all expand to the static "request->timestamp"
value, whereas I want to do wallclock timing.
I could wrap ntlm_auth in a script that times it and lots the info, but
I'm slightly wary of that - it might perturb the timings.
Any obvious/easy thing I'm missing?
Still on 2.2.0 here... anything in 3.0 I could use?
