An Error When I Use shell SshRemoteProcessRunner::readyReadStandardOutput Or SshRemoteProcess::readyReadStandardOutput signal

[F0R1X]

When I use SshRemoteProcessRunner::readyReadStandardOutput or SshRemoteProcess::readyReadStandardOutput and issue the command 'grep xxxx *', it outputs a large amount of data. Shortly after, maybe in a few seconds, I encounter the error "The remote host closed the connection." I suspect it might be related to the buffer, but I don't know how to configure it.
