Hi,

This is caused by a cache collision. This is a situation where the cache is full and starts evicting old content just as it is being used. Try increasing the size of the cache and reducing the load on your installation.

For version 4.0 we have improved the cache eviction algorithm to take not just age but also usage (hits) of the cache elements when deciding what to evict. The cache eviction now operates in an LRU+LFU (least recent used and least frequently used) mode to ensure that only the least usable data is removed.

In addition to the eviction logic improvement, we improved the file cache locking code and added support for preemptive locking. This allows the document renderer to pre-lock a cache file that it plans to work on.

These improvement reduce the probability of cache collisions by many orders of magnitude.
