# 内存诊断任务失败

#### 现象描述

内存诊断任务执行失败。


#### 可能原因

内核参数未正确配置。


#### 处理步骤

常见错误修改，确保内核中配置如下：

```
CONFIG_UPROBES=y
CONFIG_BPF=y
CONFIG_BPF_SYSCALL=y
# [optional, for tc filters]
CONFIG_NET_CLS_BPF=m
# [optional, for tc actions]
CONFIG_NET_ACT_BPF=m
CONFIG_BPF_JIT=y
# [for Linux kernel versions 4.1 through 4.6]
CONFIG_HAVE_BPF_JIT=y
# [for Linux kernel versions 4.7 and later]
CONFIG_HAVE_EBPF_JIT=y
# [optional, for kprobes]
CONFIG_BPF_EVENTS=y
# Need kernel headers through /sys/kernel/kheaders.tar.xz
CONFIG_IKHEADERS=y
```
