HI,
I guess your problem will be related to socket partition setting try increase RTCS_socket_part_max value:
/* runtime RTCS configuration */
_RTCSPCB_init = 4;
_RTCSPCB_grow = 2;
_RTCSPCB_max = 6;
_RTCS_msgpool_init = 4;
_RTCS_msgpool_grow = 2;
_RTCS_msgpool_max = 8;
_RTCS_socket_part_init = 4;
_RTCS_socket_part_grow = 2;
_RTCS_socket_part_max = 6; --> increase this value
