SELinux prevents syslog-ng OSE from using the execmem access on a process

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

setroubleshoot [21631 ] : SELinux is preventing from using the execmem access on a process. (...) python [21631 ] : SELinux is preventing from using the execmem access on a process.

To resolve this issue, switch off the PCRE JIT compile function by using the disable-jit option in the given filter or rewrite rule of your configuration.
