Hi Thomas,

Could you look into this crash dump of the OpenBTS transceiver? We're
trying to run the version from the umtrx_dual_test branch with
OsmoBTS.

using umtrx_dual_test will cause this crash. even when only using a
single trx as usual.

openbsc osmo-trx # sh /root/run.umtrx
net.core.rmem_max = 50000000
net.core.wmem_max = 524288
