Anything in your log file?  Redhat writes to /var/log/messages, Gentoo
writes to /var/log/everything/current.  Others write to who knows
what...

How about `dmesg`?  Any unusual output in there?

Any clues in the `ps` list?

Does `top` show anything spiking cpu or memory during the glitches? 
Also, keep an eye on `vmstat` `iostat` `mpstat`

If it's hard to catch, consider `sar` for collecting data.

Just thinking out loud,
