项目springboot+redis，统信uos系统
报如下错误，token:dc57e351b3654b68a6a5ec854ab8f2e8:Could not read JSON: Unrecognized token 'OK': was expecting (JSON String, Number, Array, Object or token 'null', 'true' or 'false')，然后我去redis命令行获取该key的值，并不是ok，数据是正常的，同时使用项目向redis存个字符串数据也报错，如下：
RedisSystemException: Redis exception; nested exception is io.lettuce.core.RedisException: java.lang.IllegalStateException
at org.springframework.data.redis.connection.lettuce.LettuceExceptionConverter.convert(LettuceExceptionConverter.java:74)
但是当我重启项目或者redis时问题就没有了，基本一个多月出现一次，希望遇见过该问题的朋友能给与帮助，或思路
或下次再出现此问题时 我应该怎么去排查问题？我不能重启项目也不能重启redis，因为重启任何一个 问题就可能等上一个多月才会再次出现，，
存数据时完整错误如下：
