Hi

One of our nanoBTSs startet to reboot very frequently.
The debug telnet console shows this error:

12168:WARN:OAM_RES:res_trx_status.c#231:TRX is not responding -

Another nanoBTS with same firmware and config works perfekt with the 
same openBTS installation.
Switching to the second firmware bank and flashing a different firmware 
didnt solve the problem.
Any hint where to look for more information ?
