Hi,

in a 1 ms period task of my xenomai application things work perfectly 
with my BeckHoff devices addressing them via Ethercat with EML until I 
activate rtcan. Then sometimes (not always) I get incessant warnings 
from EML which read:

EC_Telegram:: check_index(): Index field does not correspond with 
received data.
low_level_input(): framebuilding failed.

The cycle time of the task is not being violated AFAI can see.

In dmesg the following can be found when the conflict occurs

RTnet:rtskb allocation from real-time cache failed.
Assertion failed! drivers/xenomai/can/rtcan_raw.c: rtcan_tx_push:168 
dev->tx_socket=0 (3) TX skb still in use.


Can anyone make any suggestions as to what might be the problem here or 
what I could try to look at to establish this?

Regards.

Roland.
