When data is written to a channel, the writeBuffer method is invoked, and a
writeState is recorded.

WriteState records the last sent packet, which causes memory overflow.

When a large number of devices are managed and a large number of packets are
delivered last time, the cached packets delivered last time cause service
memory overflow.
