Yes, as others said, patterns are created at compile time, and every time a copy of your rulebase is deserialized. So, if you are seeing differences, either the rulebases contain different rules, or one of them was recompiled/deserialized/updated a different number of times compared to the other and something is preventing the GC to garbage collect patterns.
