lcec and Operation not permitted

I launched linuxcnc, "ethercat slaves" are in OP state, everything seems correct in the XML configuration, what could be the problem?

0  0:0  OP  +  2DM880-EC
1  0:1  OP  +  2DM880-EC
2  0:2  OP  +  2DM880-EC
3  0:3  OP  +  2DM556-EC
4  0:4  OP  +  2DM556-EC
5  0:5  OP  +  DIEWU EtherCAT-IO (Digital 16-Input/16-Output)

When running the configuration, such errors occur:

Debug file information:
Note: Using POSIX realtime

HAL: ERROR: duplicate thread name servo-thread
THREADS: ERROR: could not create thread 'servo-thread'

I tried to fix the access error:

And all lcec files installed from linuxcnc:

/usr/bin/lcec_configgen
/usr/bin/lcec_conf
/usr/lib/linuxcnc/modules/lcec.so
/etc/linuxcnc/lcec.conf
/usr/lib/linuxcnc/modules/lcec.so
