Previously the -maxConcurrentInserts was limiting the number of established client connections, which write data to VictoriaMetrics. Some of these connections could be idle. Such connections do not consume big amounts of CPU and RAM, so there is a little sense in limiting the number of such connections. So now the -maxConcurrentInserts command-line option limits the number of concurrently executed insert requests, not including idle connections. It is recommended removing -maxConcurrentInserts command-line option, since the default value for this option should work good for most cases.
