In logs of server and redis no errors. I tried different versions of server (0.4.12-dev from june and august, redis 2.8.21 and 3.0.3), i tried to edit redis config but all this not helped me. \r\nRedis log after start:\r\n```\r\n[19293] 12 Aug 00:40:53.689 # Server started, Redis version 2.8.17\r\n[19293] 12 Aug 00:40:53.689 # WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.\r\n[19293] 12 Aug 00:41:05.653 * DB loaded from disk: 11.964 seconds\r\n[19293] 12 Aug 00:41:05.653 * The server is now ready to accept connections on port 6379\r\n```\r\nIf i add string to /etc/sysctl.conf and reboot it not take effect. If i type in console sysctl vm.overcommit_memory=1 then i get error \"sysctl: permission denied on key 'vm.overcommit_memory'\" i think vds hoster is lock it. I have 4gb ram. \r\n\r\nAfter migrate to redis i see sometimes (after edit redis.conf) this new errors:\r\n```\r\n2015-08-12 06:52:03: ERROR[ServerThread]: ServerEnv: Trying to store id=31583 statically but block (-56,-74,-22) already contains 49 objects.
