J2EE shutdown, reboot - rfc, r2startup problem

Question

Hi,
I have install J2EE Engine 6.20 on a R/3 Enterprise 4.70 extension set 2.00 central instance.
I tried to start, restart and stop j2ee from smicm. "End process - with restart": works fine, after that "End process - without restart": ok. "Restart - yes": is ok, j2ee starts up. During these operations, sometimes (not always as I remember) I see these logs in sm21:

Is this a problem or just a sideeffect of the restarts?
After that I tried "Soft shutdown - with restart". Java processes disappeared, but starting up the j2ee again did not worked always. Sometimes it did not started the new java processes, sometimes it worked, in this case I could connect with Visual Administrator. During these softshutdowns these logs always appeared:

This is caused by either a) erroneous server settings, b) the backend system has been shutdown, c) network probl
ems. Will try next startup in 1 seconds.

Can somebody explain me what is wrong? If during restart the j2ee just stops and does not start, I have to stop r3
Also I have noticed these logs in Visual Administrator - server services - rfcengine:

Hello,
Does your backend system has the frfclib.o? That file should be available on the R/3 side, and not on the Portal.
Good Luck,
