2023.04.19 08:04:10.022720 [ 1 ] {} <Information> Application: It looks like the process has no CAP_IPC_LOCK capability, binary mlock will be disabled. It could happen due to incorrect ClickHouse package installation. You could resolve the problem manually with 'sudo setcap cap_ipc_lock=+ep /usr/bin/clickhouse'. Note that it will not work on 'nosuid' mounted filesystems.

It could happen due to incorrect ClickHouse package installation. You could resolve the problem manually with 'sudo setcap cap_sys_nice=+ep /usr/bin/clickhouse'. Note that it will not work on 'nosuid' mounted filesystems.
