Il problema è che faccio partire squi /service squid start) e mi da ok,ma poi non lo posso stoppare,in quanto si stoppa da solo. Se provo sia a stopparlo che a fare un service squid status,questo è quello che mi dice:
squid dead but pid file exists
squid: ERROR: Could not send signal 0 to process 3318: (3) No such process
Se faccio un riavvio della macchina,o il reset dei log (access.log,cache.log,store.log) il serivizio funziona per un po'.Ma basta una decina di minuti di navigazione per ripiantarsi e dare lo stesso errore...
Eppure i dischi non sono pieni e memoria ce n'è a bizzeffe ne lla macchina...
