Feature Request

Version v3.0.0-alpha.11 (3.0.0+a6ba41681d84d84d95eb7a377c369d709e32225b)

Problem statement.
For inspecting logs, I copy the content of log files to another location and immediately truncate the original log file. So I know what I already looked through and log files keep small.
I know that this procedure is racy, that I can miss entries. But for my living room server and media computer, this is okayish enough.

Describe the solution you'd like.
Open the logfiles (.err.log, .out.log, .wrapper.log) in append mode and allow other processes to modify the file.

Describe alternatives you've considered.
Stopping the service, copying, truncating the logs, and restating the service means a downtime.
