The "--loop" option can't work when combined with the "--fdtransfer" flag.

[zhyee]

When I use the command ./profiler.sh -e cpu,alloc,lock -o jfr --loop 60s -f %n{10000}.jfr --fdtransfer 407234 to profile my jvm process，the profiler output only one file and then stopped. I find that this is caused by the function "single_pid_server" in "fdtransferServer.cpp" source file, because it handle only one connection and then exit immediately, the subsequent connection from the profiler will be refused.
Is there any idea to avoid it.

The captured log is like below:

[WARN] FdTransferClient connect(): Connection refused
[ERROR] VM::restartProfiler fail: Failed to initialize FdTransferClient

Thank you for the report.
This configuration is not yet supported. We'll see if we can fix that in one of the next releases.

The fix has been pushed.
