Yes, that's typically the case. For example: When cron.daily runs and
all the logs are rotated, and/or the backup runs, then this might pause
an ongoing RAID-resync.

/etc/init.d/mdchk restart

Another option is to manually speed up the RAID resync:

/bin/echo 35000 > /proc/sys/dev/raid/speed_limit_min

Which might not be a bad idea either, as usually the RAID rebuild runs
at slower speeds. With the above command you can set it to a maximum
allowed 35MB/sec. Or anything else by replacing the 35000 with something
else.
