Raspberry Pi freezes roughly after 1 day and 15 hours (on average) when playing audio files (*.wav)

Raspberry Pi freezes roughly after 1 day and 15 hours (on average) when playing audio files (*.wav).

The system is running headless.
The system is running off a 3.5" HDD (powered separately).
The system does not have any devices connected except USB HDD and ethernet cable.
TP1 and TP2 Voltage is around 4.89 V.
Analogue output is being used, routed to an amplifier.
'ifplugd' package was removed/purged to save some interrupts.
The system is most up to date (apt-get update, upgrade). The kernel is latest version for now:
Linux safira 3.10.25+ #622 PREEMPT Fri Jan 3 18:41:00 GMT 2014 armv6l GNU/Linux

The mpd player is used to play *.wav files.
The music is being played only on time between 9AM till 8 PM. The Pi hangs only when playing music, on the 2nd day of uptime.

What has been done to eliminate the issue (didn't help anything of the listed):
The mpd is being stopped and started nightly by a cron script.
The music files are being played from USB HDD. I've moved it to SD card but that didn't help.
Swap space has been increased to 200 MB.
minfreekbytes in sysctl was increased to 16 MB.
The following sysctl values were set:
kernel.panic = 4
kernel.panic_on_oops = 3
Unfortunately, the Pi does not reboot after the hang up.

The only way to recover the Raspberry Pi again is to unplug and then plug the power.

After the reboot, neither syslog (syslog/messages/kern.log/auth.log or mpd.log) do not report anything.

The system is being graphed in Cacti at 5 minute intervals. The last values before the system hangs do not report anything unusual (memory/cpu/interrupts are in normal range).

If any further information or output is needed, please reply.

Does this issue still occur?

If so, what's your current kernel version? (uname -a)
As you seem to be running a kernel from raspberrypi.org, it's probably best to report it at https://github.com/raspberrypi/linux/issues as they made that kernel.
