Hi all,
I know the subject is not saying much but this is what I'm experiencing= now

After some years without any problem now I'm experiencing problems with=

I have some webservices that I use to query data on Cassandra but in the la= st
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 t= he
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 t= o
erase these data. Anyone understand wth is going on? I have no idea but mos= t of
all I don't know how to fix.

Any help would really be appreciated.

Kind Regards,
Carlo
