Too many openfiles

Hello,

We have Nuxeo 10.10 in cluster with CAS/LDAP authentication.

Each day the number of openfiles is growing. We have to restart Nuxeo for closed these openfiles othewise we have the error : Too many openfiles.

Do you have any idea to force the closure of these openfiles ? Or why do we have this problem ?

Exemple of openfiles :

lsof -u nuxeo -i

  • java 12067 nuxeo 1207u sock 0,8 0t0 1764129696 protocol: TCP
  • java 12067 nuxeo 1210u sock 0,8 0t0 1764138686 protocol: TCP
  • java 12067 nuxeo 1212u sock 0,8 0t0 1764129698 protocol: TCP
  • java 12067 nuxeo 1214u sock 0,8 0t0 1764140033 protocol: TCP
  • java 12067 nuxeo 1216u sock 0,8 0t0 1764136465 protocol: TCP
  • java 12067 nuxeo 1217u sock 0,8 0t0 1764138711 protocol: TCP
  • java 12067 nuxeo 1219u sock 0,8 0t0 1764129700 protocol: TCP
  • java 12067 nuxeo 1221u sock 0,8 0t0 1764138727 protocol: TCP

I attach 3 files with the result of netstat

netstat (command netstat) netstat_p (command netstat -p) netstat_o (command netstat -o)

I think are the connections with our LDAP's server wich causes this problem but i don't know how to prove that. After a while, i think theses connections (TCP vm-nux-server1.siden.int:41136->se-ad1.siden.int:ldap (ESTABLISHED)) become protocol: TCP and it doesn't close correctly.

Thanks.

ANSWER

Can you use netstat to find out what these connections are connecting to? That would give an indication about which code opens them.
