machine in question that did run the new beta over the weekend I see kernel messages about parity being oom-killed by the kernel.\r\n\r\nThe specs are:\r\n* 4GB of RAM\r\n* 2 vCPU Cores\r\n* machine solely for parity - besides postfix, systemd, cron & co there is nothing running on that machine\r\n* parity running with\r\n```\r\n[footprint]\r\ntracing = \"on\"\r\ndb_compaction = \"ssd\"\r\npruning = \"fast\"\r\ncache_size = 2000\r\n```\r\n* parity db is from parity-1.9.7\r\n  * parity-1.9.7 did run fine on this test machine without problems regarding memory size\r\n  * parity-1.9.7 was shut down and then parity-1.11.0 was started **without pruning db**\r\n\r\nRight before the last OOM-Kill I saw the `parity` process with 97% memory usage in `top` and `ps`.\r\n\r\nHere are the logs:\r\n\r\n```\r\n[Fri May 11 16:58:31 2018] parity invoked oom-killer: gfp_mask=0x24201ca, order=0, oom_score_adj=0\r\n[Fri May 11 16:58:31 2018] parity cpuset=/
