What can this mean?
And by the way, after working for a while Apache stops giving back
pictures, and there's nothing wrong in access log, for example:

85.141.82.175 - - [14/Oct/2007:16:11:32 +0400] "GET /img/ts.png
HTTP/1.1" 200 6330 "http://example.net/" "Mozilla/4.0 (compatible; M
SIE 6.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727)"

but in the browser picture is not displayed, as if the picture file was
broken.
In this case all I can do  stop/start Apache.

Use Apache 2.2.6 (MPM Worker), FreeBSD 6.2.
