partial GET requests consuming entire thread pool 2007-01-16 - By Roger Keays
Back
Hi there,
I'm running tc-5.5.16 and am having a problem with certain clients
consuming large numbers of ajp threads which are never released. I can
see from the httpd logs that these clients are all Windows machines and
each thread is being used to return a 16-64Kb portion of the files they
are trying to download (usually 15MB+) using a http 206 response with
the Content-Range header.
It seems the client is keeping the connections open and may be reusing
them, although not very often (nor at all efficiently). I'm not sure if
this is a standard IE feature, or if they've got some sort of download
'accelerator' installed, but it is causing quite a problem. One client
will easily consume 200 threads and my thread pool is being exhausted
rapidly.
Has anybody else had this problem?
Cheers,
Roger
