beta4 does not display some images

[Claus Guttesen]

Hi.

Have a FreeBSD 6.0 beta2 webserver that displays thumbnails. Beta2
from the 12'th of August works fine. Last night I upgraded the
webserver to beta4 as of Sept. 4'th. Some of the thumbnails were not
displayed. Simply rebooting to the older beta2-kernel resolved the
issue.

We're using the readfile-function in php5 to display the thumbnail.

There is no error-message. The thumbnails are located on a Solaris nfs-server.

regards
Claus
