If ipc.client.ping is set to true and this rpc-timeout is greater than
If this rpc-timeout is 0, it means no timeout. If this rpc-timeout is greater
than 0, and ipc.client.ping is set to true, and this rpc-timeout is greater than
the value of ipc.ping.interval, the effective value of the rpc-timeout is
rounded up to multiple of ipc.ping.interval.
