Hi,

while performing a n1ql query from cbq or from my java program I receive the kind of error written on title, can someone help me to figure out?

Query i perform from Java an cbq

SELECT * FROM default WHERE CONTAINS(adv_location, ‘Milano, MI, Italia’)=true AND CONTAINS(adv_job,‘Developer’)=true;

Error message I receive sometime from both

“errors”: [
{
“code”: 12008,
“msg”: “Error performing bulk get operation - cause: {3 errors, starting with WSASend tcp 127.0.0.1:60136: Connessione in corso interrotta forzatamente dall’host remoto}”
}
]
