Subject: how to fix constantly getting out of memory (3.11)
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
