---------------------------------

             Summary: too many open files
                 Key: NUTCH-1935
                 URL: https://issues.apache.org/jira/browse/NUTCH-1935
             Project: Nutch
          Issue Type: Bug
    Affects Versions: 2.2
            Reporter: yuanyun.cn
            Priority: Minor


This is to track the " too many open files" issue from http://lucene.472066.n3.nabble.com/Cannot-run-program-quot-chmod-quot-too-many-open-files-td4109753.html

Recently I also hit this too many open files issues, after run our crawler application for about 2-5 months, it will fail " too many open files" errors.

We have to restart nutch server and hbase.

Nutch Server opens 4249 files
lsof -p 17849 | wc -l
4249

There are a lot of pipe, sock, and connections to hbase.

cat sorted | grep pipe | wc -l
1624
cat sorted | grep 2181 | wc -l 
813

907 java    17849 user 1465u  sock                0,7      0t0 65043894 can't identify protocol
1843 java    17849 user 2744u  IPv6           76971706      0t0      TCP localhost:35073->localhost:2181 (ESTABLISHED) // connect to hbase

cat sorted | grep anon_inode | wc -l
812

Thanks...
