Temp OOM's on 1.8.1
We are using 1.8.1 Enterprise for eval and finding that when memory is getting tight on Couchbase we start to get a lot of Temp_OOM and then things go badly in our application.
We have fairly large values at ~30KByte each, and are generating new k/v at a max of 150 per second, and doing a get (and touch - resetting TTL) on ~150/s as well.
We have sized the bucket with 180GB RAM and 1.5TB of SSD for persistence.
I am a bit baffled why we can't sustain even 150 sets/sec and 150 gat/sec as if we switch back to a simpler back end for k/v like leveldb we can get 45K/s without issues on the same SSD back end.
We are using the C libcouchbase client code as well - should it be handling these temp_oom issues better?
