Hi i'm using a 3 node cluster of cassandra 0.6.1 together with hector as api to java client.
every few days I get a situation where I cannot connect to cassandra, other than that the data dir is filling up the whole disk space and the synchronization stops at these times, the exceptions I get are as following: Happended 3386 in 24H: POOL EXHAUSTED: 02:00:30.225 [MyThread[5]]: Unable to connect to cassandra node xxx.xx.xx.32:9160 will try the next node, Pool exhausted Happened 6848 in 24H CONNECTION REFUSED: 06:14:48.598 [MyThread[4]]: Unable to connect to cassandra node xxx.xx.xx.30:9160 will try the next node, Unable to open transport to xxx.xx.xx.30:9160 , java.net.ConnectException: Connection refused: connect Happened 84 times in 24H: NULL OUTPUTSTREAM: 06:14:48.504 [MyThread[2]]: async execution fail, Cannot write to null outputStream Happened 14 times in 24H: CONNECTION TIMED OUT: 06:15:08.019 [MyThread[0]]: Unable to connect to cassandra node xxx.xx.xx.31:9160 will try the next node, Unable to open transp ort to xxx.xx.xx.31:9160 , java.net.ConnectException: Connection timed out: connect Can anyone assist or suggest what could be the problem? note that the node is funcioning well and it happens once every few days.
