Hi Evan,I set swt very_low and zdbbl to 64MB, setting this params helped reducing the busy_dist_port and Monitor got {suppressed,... Messages a lot. But when the performance of the cluster suddenly drops we still see these messages.
The cluster was updated to 1.3 in the meantime.
The eleveldb section:
%% eLevelDB Config
{eleveldb, [
{data_root, "/var/lib/riak/leveldb"},
{cache_size, 33554432},
{write_buffer_size_min, 67108864}, %% 64 MB in bytes
{write_buffer_size_max, 134217728}, %% 128 MB in bytes
{max_open_files, 4000}
]},
the ring size is 1024 and the machines have 48GB of memory. Concerning
the params from vm.args:
-env ERL_MAX_PORTS 4096 -env ERL_MAX_ETS_TABLES 8192 +P isn't set Ingo Am 03.04.2013 16:53, schrieb Evan Vigil-McClanahan:
For your prior mail, I thought that someone had answered. Our initial suggestion was to add +swt very_low to your vm.args, as well as setting the +zdbbl setting that Jon recommended in the list post you pointed to. If those help, moving to 1.3 should help more. Other limits in vm.args that can cause problems are +P, ERL_MAX_PORTS, and ERL_MAX_ETS_TABLES. Are any of these set? If so, to what? Can you also pate the eleveldb section of your app.config?

Are there any other messages that appear around this time that might indicate why?
