win32: Truncated files

I've just found out a weird behaviour in my test server: large files always
get truncated.

Large means more than 100 KB (aprox.). According to logs the complete file
is transferred but the browser (whatever browser, it doesn't matter) only
displays the first bytes (12,000 bytes... 40,000 bytes; the exact figures
differs from file to file but it's always the same in a given file). It
happens with all MIME types (pictures, text...) and all browsers (Explorer,
Mozilla...). If I upload the file to a remote Apache server, the problem
disappears.

The comptuer runs Windows XP Professional. I upgraded from 2.0.46 to 2.0.56
but it didn't help.

I'd really appreciate any hint. I haven't been able to find the correct
keywords for Google :(

Guess you have mod_deflate running, without failure starts just below 8k.
IIRC the failure caused by a single byte is dropped out off the stream
about every 8k, so some errors in the transferred HTML may not be
noticed -or even not be noticable-.

Starting version 2.0.49 -so in a way your update may have helped - a single
option to many problems arising from third party fire-walls -ZA5 is kown for
ill behaviour- and anti-virus software is available
http://httpd.apache.org/docs-2.0/mod...isableacceptex

Good guess, however the module is not active.

My error log was displaying the "winnt_accept: Asynchronous AcceptEx
failed" message mentioned in the URL so I've added the directive and
restarted Apache. However, files are still being truncated :(

Some more info I've gathered: the file is not actually truncated, it is
messed. The size of the received file is the correct one but its contents
seem to repeat cyclically. E.G., if the file is:

Line 1
Line 2
Line 3
Line 4
Line 5
Line 6

What I get is:

Line 1
Line 2
Line 3
LinLine 1
Line 2
Lin
