Hi Alexander,
Thanks for your response. We use multi-backend with bitcask and leveldb.
- File descriptors seems to be ok, at least the config.
ubuntu@ip-10-2-58-5:/var/log/riak$ sudo su riak
sudo: unable to resolve host ip-10-2-58-5
riak@ip-10-2-58-5:/var/log/riak$ ulimit -n
65535
- Memory seems to be ok as well:
KiB Mem: * 15400916 *total,* 14493744 *used,* 907172 *free,* 36244 *
buffers
- Disk is ok
/dev/xvda1 20G 4.1G 15G 22% / # root device
/dev/xvdb 148G 69G 72G 49% /mnt/riak-data # bitcask and riak
data disk
/dev/xvdc 296G 23G 258G 8% /mnt/riak-data/leveldb #leveldb disk
Any other idea? Thanks.
