No FreeBSD crash data found.

da oltre un anno non ho mai avuto errori e sono installati:

• haproxy (utilizzato solo come reverse proxy)
• FreeRADIUS
• Squid (trasparent proxy)
• squidGuard
  ci sono 8gb di ram e al momento oltre il 50% disponibili, ma ad ogni errore la ram disponibile sembra scendere;
  dall'errore "Unknown on line 0" non riesco a capire da cosa sia dovuto !!

Grazie dell'aiuto
