This was triggered by turning off encryption on ACL link when rfcomm was using high security. rfcomm_security_cfm (which is called from rx task) was closing DLC and this involves sending disconnect message (and locking socket). Move closing DLC to rfcomm_process_dlcs and only flag DLC for closure in rfcomm_security_cfm.
