1.Too many open files错误：原因是默认允许的最多同时打开文件限制为1024，通过命令ulimit -n 1000000，问题解决。

ulimit -a可以查看同时允许打开的文件数，对应下图中“open files”

root@DESKTOP-90KJ7MS:/usr/src/openharmony4.0/OpenHarmony-v4.0-Release/OpenHarmony# ulimit -a

2. die__process_unit错误：原因是WSL虚拟机默认内存大小不够导致，通过调整WSL内存大小为12GB，问题解决。

die__process_unit: DW_TAG_label (0xa) @ <0xf8> not handled!

die__process_unit: tag not supported 0xa (label)!

die__process_unit: DW_TAG_label (0xa) @ <0x1cd> not handled!

die__process_unit: DW_TAG_label (0xa) @ <0x1ef> not handled!

 在开始搜索栏输入%UserProfile%，在打开文件夹中添加.wslconfig文件，文件内容如下

[wsl2]
memory=12GB
swap=12GB
localhostForwarding=true

WSL虚拟机需要重启，可以在Power shell中输入wsl --shutdown，然后在启动Ubuntu即可生效。可以通过free -m命令进行查看

root@DESKTOP-90KJ7MS:/usr/src/openharmony4.0/OpenHarmony-v4.0-Release/OpenHarmony# free -m
              total        used        free      shared  buff/cache   available
