Thanks, a lot everyone!

Performance looks good now. No deadlocks and nothing being purged from the cache. I have started pointing more sssd clients at the cluster.

Thanks,

Only four clients are currently using this cluster so perhaps I should actually use DB_CONFIG before putting it into production.

Maybe you could start considering this from a moderately loaded and sized server: set_cachesize 0 15000000 1 set_lg_regionmax 262144 set_lg_bsize 2097152 set_flags DB_LOG_AUTOREMOVE set_lk_max_locks 30000 set_lk_max_objects 30000

Also note "olcDbConfig: <DB_CONFIG setting>" is probably the modern way to do it.
