# SELinux prevents using the execmem access on a process

If you are using a recent enough PCRE library, AxoSyslog will automatically use the JIT of the regexp engine, which will result in a similar error:

```shell
   setroubleshoot [21631 ] : SELinux is preventing <syslog-ng path> from using the execmem access on a process. (...)

    python [21631 ] : SELinux is preventing <syslog-ng path> from using the execmem access on a process.
```

To resolve this issue, switch off the PCRE JIT compile function by using the [disable-jit](https://axoflow.com/docs/axosyslog-core/4.28/chapter-manipulating-messages/regular-expressions/reference-regexp-types/index.md#pcre-flags) `flags()` option in the given filter or rewrite rule of your configuration.
