same issue with :

Percona-XtraDB-Cluster-client-56-5.6.35-26.20.2.el6.x86_64
Percona-XtraDB-Cluster-shared-56-5.6.35-26.20.2.el6.x86_64
Percona-XtraDB-Cluster-56-5.6.35-26.20.2.el6.x86_64
percona-toolkit-2.2.15-2.noarch
Percona-XtraDB-Cluster-galera-3-3.20-2.el6.x86_64
percona-xtrabackup-2.3.5-1.el6.x86_64
Percona-XtraDB-Cluster-server-56-5.6.35-26.20.2.el6.x86_64

both configuration generate 300+ gcache.page.000* logs

1 wsrep_provider_options = gcache.size=2G;gcache.keep_pages_size=100M;gcache.keep_pages_count=20
2 wsrep_provider_options = gcache.size=2G;gcache.keep_pages_size=2GB;gcache.keep_pages_count=10

any suggestion ?
