INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10

Memory block header corruption running query with bson_get()

The af file block header dump looked like the following:

13:48:44  Found during mt_shm_free 1
13:48:44  Pool '44' (0x468af040)
13:48:44  Bad block header 0x47771050

13:48:44  Bad block removed from pool

And was produced by the following SQL statement:

SELECT SKIP 0 LIMIT 2 data FROM foo
WHERE (bson_get(data, 'orgId') =
        '{ "orgId" : "5592bfade4b0cc601fe23133" }'::json::bson
    )
    AND (bson_get(data, 'refId') =
        '{ "refId" : "55688e84e4b01e28da75d233" }'::json::bson
    )
    AND (bson_get(data, 'refVersion') =
        '{ "refVersion" : 14 }'::json::bson
    )
    AND ((bson_get(data, 'name') =
        '{ "name" : "56cf552ce4b0e91a0f73037b" }'::json::bson)
        OR (bson_get(data, 'configId') =
            '{ "configId" : "56cf552ce4b0e91a0f73037b"
}'::json::bson
        )
    )

So, it appears that the last part of the query string has
overwritten the block header.
