it looks like a staled session, sleeping in a "condition wait" (SM_READ, shared memory reading ). Sessions may wait on conditions; and there is no acturate waiting time, only the expecting event can invoke the "sleeping on condition wait" session. Normally, it should not wait a long for shared memory reading, since the 'latch' or semaphore on a share memory resource, say mutex, hash table etc, should be done in very short time. Internally it may wait on a semaphore. I guess, it may be either an Informix bug or a OS patch need to be installed. |
