Spring Boot Admin 3.5.0大量超时及异常问题排查求助

各位大佬好，我在使用Spring Boot Admin 3.5.0监控服务时，遇到了一个棘手的问题：系统里不断出现大量标记为INFO或WARN级别的错误日志，核心都是超时和异常情况，不仅严重影响了日志的可读性，我也担心会不会埋下潜在的稳定性隐患。以下是我截取的关键日志内容：

目前我梳理了下，这些异常主要分为两类：

• StatusUpdater和InfoUpdater的请求超时问题，分别在9000ms和10000ms时触发
• IntervalCheck的OverflowException，提示定时任务的tick生成速度快于下游请求的处理速度，导致tick无法正常发送

想请教下有没有朋友遇到过类似的情况？或者有没有配置调整的方向，比如延长超时时间、调整调度器的参数，能解决这些问题？
