We have 2 clusters in which we've upgraded logstash to version 1.5.3 and since then logstash broker, which put data to redis, hangs every 4-5 hours. The process is still in memory, no errors are shown in log file, but the no data is being written to redis. After I restart it, broker starts working properly, until it again hangs. It takes couple of hours to happen again.

Any help will be appreciated.

Below is my config file.

input {  
file {  
type =\> "syslog\_product"  
path =\> ["/data/product/\*"]  
sincedb\_path =\> "/data/sincedb"  
}

}

output {

stdout {}

redis {  
host =\> ["redis-host"]  
data\_type =\> "list"  
key =\> "product:syslog\_product"  
type =\> "syslog\_product"  
batch =\> true  
batch\_events =\> 2000  
workers =\> 16  
}  
}
