Hi, I have seven nodes, debian stretch with c*3.11, each with 2TB disk (500G free), 32G Ram. I have a keyspace with seven tables. At the moment the cluster doesn't work at all reliably. Every morning at least 2 nodes are shut down due to out of memory. Repair afterwards fails with "some repair failed". I use G1 with 16G heap on 6 six nodes and cms with 8G heap on one node to see a difference. In munin it's easy to see a constantly rising memory consumption. There are no other services running. I cannot understand who is not releasing the memory. Some tables have some big rows (as mentioned in my last mail to the list). Can this be a source of the memory consumption?
How do you track down this? Is there memory which doesn't get released and accumulates over time? I have not yet debugged such gc/memory issues. cheers Michael --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@cassandra.apache.org For additional commands, e-mail: dev-h...@cassandra.apache.org
