I'm facing the errors below for 2 months: ModSecurity: Audit log: *Failed to lock global mutex: Invalid argument* [hostname "xyz.com"] [uri "/some/url/index.php"] [unique_id "YoVhNjBIlODXmbU8zRObNAAAAAo"] ModSecurity: Audit log: Failed to *unlock* global mutex: Invalid argument [hostname "xyz.com"] [uri "/some/url/index.php"] [unique_id "YoVhNjBIlODXmbU8zRObNAAAAAo"] In the audit log I have the following: > --4f737934-A-- > [18/May/2022:21:12:23 +0000] YoVhNjBIlODXmbU8zRObNAAAAAo 98.142.102.10 > 55052 172.31.20.202 443 > --4f737934-B-- > POST /some/url HTTP/1.1 > Host: xyz.com > Accept: */* > Content-Length: 7 > Content-Type: application/x-www-form-urlencoded > > --4f737934-C-- > token=0 > --4f737934-F-- > HTTP/1.1 401 Unauthorized > Cache-Control: no-cache, private > Content-Length: 19 > Content-Type: text/html; charset=UTF-8 > > --4f737934-H-- > Message: Audit log: Failed to lock global mutex: Invalid argument > Apache-Error: [file "apache2_util.c"] [line 273] [level 3] [client > 98.142.102.10] ModSecurity: Audit log: Failed to lock global mutex: Invalid > argument [hostname "xyz.com"] [uri "/some/url/index.php"] [unique_id > "YoVhNjBIlODXmbU8zRObNAAAAAo"] > Apache-Handler: application/x-httpd-php > Stopwatch: 1652908342996576 5468 (- - -) > Stopwatch2: 1652908342996576 5468; combined=1343, p1=443, p2=721, p3=0, > p4=0, p5=178, sr=83, sw=1, l=0, gc=0 > Producer: ModSecurity for Apache/2.9.3 (http://www.modsecurity.org/); > OWASP_CRS/3.2.0. > Server: Apache > Engine-Mode: "ENABLED" > I read it was related to logrotate. I tried to add "Mutext default" line to apache2.conf, also tried to use "Mutex posixem" to fix another mutex related error (AH02026: Failed to acquire SSL session cache lock)... I simply don't know what else to do to solve the problem, or if it's safe enough to disable mod_security. Any help is appreciated. System: Ubuntu 20.04.4 LTS Apache: 2.4 |
