> Closed segments leak memory as eviction does not remove these segments from closed segments list.
> {code}
>  void evictCache(long[] followerIndices, long flushedIndex,
>       long lastAppliedIndex) {
>     List<LogSegment> toEvict = evictionPolicy.evict(followerIndices,

>     for (LogSegment s : toEvict) {
>       s.evictCache();
>     }
> {code}
> After the segments have been marked for eviction, they should be removed from queue as well.
