Hi, thank you very much for suggestions. It seems to be OK. I set the FSM related variables 200 times higher then the default values. The database has been working stable for 3 days. Just as before, when the databas was empty. BTW, isn't it too high to increase these values to 200 times higher? What kind of problems it can cause? -- Csaba -- No virus found in this outgoing message. Checked by AVG Anti-Virus.
