HarmonyOS 鸿蒙Next HI3861上socket数据解析过程，发生KERNEL PANIC No suitable free block, require free node size:
HarmonyOS 鸿蒙Next HI3861上socket数据解析过程，发生KERNEL PANIC，大神帮看下是啥原因：[ERR] [OsMemAllocWithCheck] No suitable free block, require free node size:
hi3861开发板上socket高频通讯出现以下问题（注：程序中主要逻辑是解析和打印数据包），求助！无可用内存块么：
[ERR] [OsMemAllocWithCheck] No suitable free block, require free node size: 0x128<button style="position: absolute; padding: 4px 8px 0px; cursor: pointer; top: 8px; right: 8px; font-size: 14px;">复制</button>

内存问题没了，但出现了watchdog问题：

在HarmonyOS鸿蒙系统上，遇到KERNEL PANIC通常表明内核遇到了无法恢复的错误。您提到的[ERR] [OsMemAllocWithCheck] No suitable free block, require free node size:错误提示表明在内存分配时找不到足够大的空闲块。这可能是因为：
- 内存碎片严重，导致虽然总内存足够，但无法找到连续的大块内存。
- 应用程序或其他服务占用了过多内存，导致可用内存不足。
建议检查以下几点：
- 审查内存使用情况，查看是否有内存泄漏。
- 优化内存管理策略，减少碎片化。
- 评估是否有必要增加系统内存或优化内存分配逻辑。
