Das Verhalten ist so schlimm, das redis im Datei Bereich der Nextcloud nicht mehr zuverlässig läuft. Ich bekomme die Meldung das die dateien gelockt sind. Redis-cli zeigt:
root@office:/var/log/redis# redis-cli -s /var/run/redis/redis-server.sock MONITOR
(error) ERR max number of clients reached
Error: Connection reset by peer
Wenn ich die App client_push deaktiviere kann ich wieder normal arbeiten.
root@office:/var/log/redis# service notify_push stop
root@office:/var/log/redis# redis-cli -s /var/run/redis/redis-server.sock MONITOR
OK
Weiss jemand einen Rat?
change maxclients in /etc/redis/redis.conf von 512 —> 10000
ein schuß aus der hüfte
lg
oder sogar noch etwas höher
