Bug Description
snapshots.l.o quite often gets stuck at 100% cpu load. TOP reports apache is 100% cpu loads, which obviously after a while load average increases to over 40.00.
Example:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
4487 www-data 20 0 937m 69m 7644 S 33.9 1.9 10:15.45 apache2
6533 www-data 20 0 935m 45m 6024 S 32.9 1.2 0:35.55 apache2
4459 www-data 20 0 938m 70m 7640 S 32.5 1.9 6:30.87 apache2
I have included a 2 week screenshot from cloudwatch showing the CPU usage. I have had a look at the apache logs at the time of cpu spikes, and there is to abnormal activity to report.
The problem is, when the server gets stuck in in this state, it often hangs and causes http timeouts. Restarting apache causes the load not to drop. The cpu can be at 100% for a few hours, before it decides to drop again.

The download links on android build page are not functional when the load is high on snapshots.
