OpenLiteSpeed Cache is ignoring No Cache URI

Hello so we have a situation with XML Feed which is cached by the Plugin.
We have set rules to disable Caching in Do Not Cache URIs

/feed/
/feed
^/feed/$
^/feed$

But it still generates cache file for XML Feed.
Also there is a strange error in vhost error log

[Module:Cache] createEntry failed.

The only solution is to delete everything from /usr/local/lsws/cachedata/priv and restart OpenLiteSpeed.
