Laszlo Hornyak commented on CXF-6160:
-------------------------------------
Hi Sergey,
I haven't experienced the problem with one request only. It does not always hit
even with 20000, in fact I hammered the application with a series of requests
until it died, but that always happened in the first 50000 requests. That some
out of tens of thousands would certainly be a minor problem for most cases, but
the server threads are stuck and consuming CPU time and in a few hundred
thousand requests the application dies.
Also, one does not have to send requests in parallel, ab with single thread
concurrency does it.
Regards,
Laszlo
