The queue system selects storing positions in a memory (2), performs write operations (4) on the storing positions from an on-line maintained idle list (6) of addresses to free storing positions in the memory. The system calculates addresses for collecting (8) data earlier stored in memory. The storing positions are exposed to a test procedure (16) which is performed periodically on each storing position in idle cycles during operation of the system. The result of the test procedure is used for maintenance of the idle list (6). The addresses selected for test are released from system use as controlled by the system. The test of a storing position may be performed after awaiting for it to have been released from use by the system, and return to system use is performed only if the storing position, only if the storing position stands the test. |
