Does the entire operating system crash?
If so, have you reported this to FreeBSD?
Could you post the link to that bug report?

I am having the same problem on a FreeBSD 7.0-STABLE box.

Replying to Olaf van der Spek:

- No I have not made a bug report.

The system becomes unresponsive (http|ssh(new and current sessions))
I can however still ping the machine.
I am sitting remotely and can only cut the power to make it reboot.
The freeze will happen even if uploads is disabled in php. Though I have not been able to reproduce the problem when posting a fileupload to a static html file.

I have made struss and strace outputs. but to me they are just nonsens :)
I will try to attach the strace file as it seems to have a peculiar ending.

For my, lighttpd never crashed/hanged my FreeBSD 6.3 server. I had to change
server.network-backend = "write"
so that POSTs work up to 50MB (haven't tested the maximum). Otherwise they would simply get stuck after uploading some 100kB. I'm using perl though, not php.

Replying to uspoerlein@gmail.com:

server.network-backend = "write"

I have now had this setting for two days without a lockup/crash.

It seems to have done the trick.

I will keep a close eye on the system for a few days then report back.

Thanks.

I have the same problem, with same results:

server pingable, ssh and web-server down.

nmap show port 22 and 80 open

I found out the server had been upgraded from FBSD6 to FBSD7.
I tried reinstalling all ports suspecting some library weirdness.
When it didn't help I reinstalled the hole OS (Wintendo style fix,
but a fix non the less).

This was in fact a FreeBSD bug (http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/138999) and was fixed upstream (FreeBSD svn r198853 in HEAD, and merged to RELENG_8 in FreeBSD svn r199356; and RELENG_7 in FreeBSD svn r199358).
