Description

Exemple, avec httpworkers = 5000 ("bonne valeur pour un serveur moyen") :

2017-09-04T12:27:31.103527+02:00 amon.etb1.lan eole-guardian[23812]:  * Starting e2guardian
2017-09-04T12:27:31.104307+02:00 amon.etb1.lan eole-guardian[23812]:  * Instance #guardian0
2017-09-04T12:27:42.200836+02:00 amon.etb1.lan eole-guardian[23812]:  httpworkers option in e2guardian.conf has a value too high for current file id limit (8192)
2017-09-04T12:27:42.201027+02:00 amon.etb1.lan eole-guardian[23812]: httpworkers 5000 must not exceed 50% of 8183
2017-09-04T12:27:42.201188+02:00 amon.etb1.lan eole-guardian[23812]: in this configuration.
2017-09-04T12:27:42.201366+02:00 amon.etb1.lan eole-guardian[23812]: Reduce httpworkers
2017-09-04T12:27:42.201479+02:00 amon.etb1.lan eole-guardian[23812]: Or increase the filedescriptors available with ulimit -n to at least=10009
2017-09-04T12:27:42.207464+02:00 amon.etb1.lan eole-guardian[23812]:    ...fail!

J'ai essayé d'augmenter la clé "LimitNOFILE" dans le .service mais sans succès.
Pourtant cela semble être la solution : https://github.com/e2guardian/e2guardian/issues/208
