After some years without any problem now I'm experiencing problems with counters but, the most serious problem, is data loss immediately after a read. I have some webservices that I use to query data on Cassandra but in the last month happened 2 times the following problem: I call my WS, it shows data. I refresh the page -- data are no more available! I can call then 200 times the WS but I won't see data anymore ... today my colleague experienced the same problem. The WS are ABSOLUTELY read only on the DB and there are no write to erase these data. Anyone understand wth is going on? I have no idea but most of all I don't know how to fix. Any help would really be appreciated. Kind Regards, Carlo
