<br>
These are the affected lines in my config:<br>
filter f_avc { message(".*avc: .*"); };<br>
filter f_audit { message("^(\\[.*\..*\] |)audit.*") and not<br>
message(".*avc: .*"); };<br>
filter f_pax { message("^(\\[.*\..*\] |)PAX:.*"); };<br>
filter f_grsec { message("^(\\[.*\..*\] |)grsec:.*"); };<br>
<br>
These are there for a long time now, but obviously needs a treatment to<br>
make them up-to-date.<br>
There are multiple messages during startup:<br>
"multi-line-pattern: Error while JIT compiling regular expression"<br>
and more.<br>
<br>
If I try to add disable-jit, the messages persist. So it seems syslog-ng<br>
still try to use jit. Despite the messages the software is still<br>
functional as intended. I just want to instruct it not to try<br>
jit-optimizing the expressions, hence get rid of the messages.<br>
<br>
Thanks:<br>
