Hallo,
mein mysql service stürzt manchmal ab.
Das Prozedere ist folgendes:
- Zuerst öffnet mein Datenbank user immer mehr Connections auf die Datenbanken (Mit Sleep als Command).

±-------±------------±----------±-----------±--------±-----±------±-----------------+ - Die Load meines Servers steigt.
- Normale Abfragen werden nur noch langsam abgearbeitet >17 Sekunden pro Abfrage.
- Load ist bei 100-200.
- MySQL stürzt ab, Server startet sich neu.
Hier ist ein mysqladmin extended-status:
