Lighttpd 1.4.15 crashes when file transfer under OpenBSD 4.0

[atma]

Hello,

I have OpenBSD 1.4.15 installed (manually from src) on an OpenBSD 4.0 (stable). The lighttpd-1.4.15 crashes when I try to download large files. I download via Torrentflux (a torrents client written in PHP) with Firefox/IE on Win32. After after a short-time downloading, which varies from 2 to 90 seconds the httpd stops working. Unfortunatelly I can't find any logs that (in my opinion) are related with the crash on /var/www/logs/ which resides lighttpd.error.log file.

When I use the version 1.4.11 (precompiled binary for OBSD) everything works smoothly, I get like 10,4 MB/s speed, downloading the same file which the former lighttpd server crashes.

Regards,

Thank you for the amazing piece of software :-)
