Sounds like you need to increase the Heap size and/or reduce the memtable_throughput_in_mb and/or turn off the internal caches. Normally the binary memtable thresholds only apply to bulk load operations and it's the per CF memtable_* settings you want to change. I'm not familiar with lucandra thoug

Hi community, during my tests i had several OOM crashes. Getting some hints to find the problem would be nice. First cassandra crashes after about 45 min insert test script. During the following tests time to OOM was shorter until it started to crash even in "idle" mode. Here the facts: - cassa
