I had this problem a while back. The problem isn't with apache as such, more that your system isn't random enough...

At start, apache reads /dev/random to get data to generate the digest for mod_auth_digest. If /dev/random hasn't got enough random data in it, it blocks until it does, which is why apache appears to hang.

/dev/random gets data from entropy in the machine (random events like interrupts). I was running downstairs to the machine and mashing the keyboard to give it enough data until I just commented out the mod_auth_digest module.

The reason why "MY_BUILTINS="--with-devrandom=/dev/urandom" emerge apache" works is that /dev/urandom does not block, so it will return the contents even if less than requested, at a cost to randomness.

Thanks for that posting. Explains my problem. Same symptoms. Haven't re-emerged yet and probably won't.
But I will try those methods explained in the bug. Seems fairly interesting that a "du -h /anypath" can produce some entropy for the digest key...

I had the same problem and the /dev/urandom fixed it!

i had the same symptoms described here. After trying eveything discussed here it still didn't work.

Fixed it though

for ppl with the same problem, i emerged php 4.3.7 yesterday and it broke after reboot. without php it worked fine. Seems you have to re-emerge turcks-mmcache if you have that installed. Probaby dbg also if used.

Hello all,

I had the same problem. I had already installed apache and I got the problem with the apr package. I solved the problem with the folloing:

USE="urandom" emerge apr
