-------------------------------------------
Good catch Mukul. After applied the patch, TestRaftWithSimulatedRpc fails with
{code}
java.lang.IndexOutOfBoundsException: startIndex = 0, log cache starts from
index 3048
{code}
Please take a look.
Please run all the locally since Jenkins is not yet setup completely.

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