小弟有一SQL语句现在在多并发的情况下会出现死锁。希望各位大神帮忙给小弟分析一下。

UPDATE accountinfo SET usecnt = 20, version = version+1 WHERE usecnt > 0 AND accountid = 12 and version = 102

其中accountid为主键，usecnt和version没有任何索引。
当前事务使用的事务隔离级别为：READ_COMMITTED

发生死锁的日志如下：

*** (1) TRANSACTION:
TRANSACTION 1331664, ACTIVE 40 sec starting index read

*** WE ROLL BACK TRANSACTION (2)

请各位大神，帮小弟看一下。怎么破。

补充：
explain UPDATE accountinfo SET usecnt = 1999, version = version+1 WHERE usecnt > 0 AND accountid = 12 and version = 102
