ModSecurity blocks requests

[ponasromas]

When enabling mod_security there is strange problem with connection. After enabling it, few minutes latter all connections timing out.

It is easy to reproduce:

1. Install nginx with modsec enabled;
2. Load modsec:

modsecurity         on;
modsecurity_rules_file /etc/nginx/modsec/main.conf;

3. Visit your website, few pages. Eventually you will encounter infinite loading and timeout.

Maybe related, error.log contains:

2021/02/13 10:17:53 [alert] 31891#31891: *330 open socket #37 left in connection 8
2021/02/13 10:17:53 [alert] 31891#31891: *329 open socket #35 left in connection 9
2021/02/13 10:17:53 [alert] 31891#31891: aborting

I think it would be more useful to report this in https://github.com/SpiderLabs/ModSecurity than here
