Just upgraded a box to 29, and I've spotted the following in the httpd
section of my Logwatch email:
Unescaped left brace in regex is deprecated here (and will be fatal
in Perl 5.32), passed through in regex; marked by <-- HERE in m/\G%({
<-- HERE .*?})?./ at /usr/share/logwatch/scripts/services/http line
319.
It does, however, appear to have successfully rotated the httpd
logfiles and restated httpd without incident, but may be a pointer as
to what might be going wrong on your server.
