| |
All,
I moved from kernel 2.6.25.4 to 2.6.26 yesterday and observed that large files sent via Apache2 are partially corrupt.
This appears to be linked to sendfile() -- disabling the use of sendfile in the apache config (EnableSendfile Off) allows it to function as normal.
My system is a simple Core2Duo running Debian lenny/sid; nothing special, and I have never observed problems like this before.
The problem feels certainly related to sendfile() since the data reads correctly from disc in other programs, and via CIFS etc.
The corruption happens part-way in to the file... I've no exact figure but it would seem like maybe 32KB -- I'm seeing broken PNGs served from Apache, where the top few dozen lines decode correctly, and the rest is garbage.
I've made basically no configuration changes between 2.6.25.4 and 2.6.26 and have explicitly tried both enabling and disabling the new PAT support to no effect.
This is completely repeatable and reproducible.
Is anyone else seeing this broken behaviour?
Ian.
