why response assertion failure: "response was null"?

[Will Milspec <wi...@gmail.com>]

Hi all,

This second error/issue/puzzle I found tonight pertained to  "failure true"
response assertions when jmeter downloaded some javascript files.

some points
-The access logs show successful downloads for all requests to said file
(tiny_mce_src.js)
-The jmeter jtl log records some successes, some failures for this file.
-if the server timed out, and the http client thought it received "null" or
an empty string, I would have the status code would say something (and the
error message would likewise differ)

What does this "response assertion failure" mean (httpclietnt got nothing
back, that it took too long,etc) ? Could jmeter have run out of resources?
Could the server simply have taking too long and this "response assertion
failure" is in fact a time out. (i.e. and a signal to beef up the server
resource)

thanks

will

rc=204 - HTTP code 204 No Content
by = 0 = zero bytes in response.
