unserialize error in DB_cache.php

Code:

An error occurred:

error - 2013-12-23 10:04:59 --&gt; Severity: Notice  --&gt; unserialize() [<a href='function.unserialize'>function.unserialize</a>]: Error at offset 16385 of 16384 bytes /home/xxxx/public_html/system/database/DB_cache.php 108

I've been seeing these messages recently in my error log randomly. Site fuctions are working fine and i have been having trouble (not able to replicate) replicating the issue on the controller/method where the cache error occurs.

Any idea as to what's going on?

I've seen this happen when too much data is being put into session and it gets chopped off, so unserialize can't do its thing since the serialized string is broken.

Are you using cookies or the database for session storage?

Db storage of sessions.
