Hi
That's the same that is happening with me since about two weeks, and I was unable to solve it. They told me it might be uhd problem, but I installed different uhds with the same issue.
osmo-bitb shows the same error like this:
<0000> chan_alloc.c:342 (bts=0,trx=0,ts=7,pchan=TCH/F) Allocating lchan=0 as TCH_F

<0004> abis_rsl.c:767 (bts=0,trx=0,ts=7,ss=0) is back in operation.
it once showed this error:

<0000> chan_alloc.c:355 Failed to allocate SDCCH channel
<0004> abis_rsl.c:1678 BTS 0 CHAN RQD: no resources for SDCCH 0x10
osmo-pcu is not working fine with me, can this help to solve the problem?, this is the output for using it with and without sudo.

I use USRP2 , I used recently a reference clock of 10 MHz but didn't solve the issue, but it is good to know that N210 is with the same error.
Another thing that my network rarely shows on the MS, but the osmo-nitb still shows the output every minute or more or when I do a mobile network search.
Thanks
