Hello!

>The customer refers to a cfserver.log logfile which doesn't exist.

it doesn't?:

andy@cornholio:/usr/local/coldfusionmx/logs$ ls
application.log  cfserver.log  exception.log  server.log

>>I do see the stack traces he refers to in
\cfusionmx\runtime\logs\default-event.log (JRun log file).  When holding
down F5, it grows at >>a rate of 300 kilobytes per minute.  
>>I don't view this as a DoS attack for three reasons:

it was not the file growth I was refering to with respect to the DOS
 
>>3) I can't get the server to actually crash.  

It does on my setup - ok, it does not crash as in segfault, but the CF
server does not server pages

>>I did notice, with debugging on (as the customer appears to have),
that it does take a lot longer for the server to recover after you
>>nail it with so many concurrent requests.  

very true, however i have found a point, which is usually under 10
seconds worth of holding down F5, where the server does not recover

>My recommendation to the customer would be to  a) limit debugging by IP
Address in the CF Admin  b) tune the JRun throttle so that
>threads stuck in the queue for a while get timed-out earlier.  This is
modified in jrun.xml: <attribute name="threadWaitTimeout">300
></attribute>.  The default value of 300 seconds could be limited to 20
seconds or less.

excellent, thanks, I will try that.  I presume there is no nice web GUI
for doing jrun admin on a CFMX install, if so is there a list of
tweakable options?

thank you very much for all your help in this matter, much appreciated

all the best

andy
