Keep seeing the same line -----Original Message----- From: André Warnier (tomcat/perl) <a...@ice-sa.com> Sent: Saturday, May 22, 2021 10:22 AM To: users@tomcat.apache.org Subject: Re: apache-tomcat-8.5.59 too many open files on Linux 8 Mmm. Nothing very special in that netstat output. The sockets seen there look quite normal for tomcat, and there are not a lot. What about the IPv4 sockets ? (remove the -6 in your netstat command) Looks like lsof is counting things which are not IPv6 TCP sockets belonging to the tomcat JVM process. Where is the difference between the lsof count (19948) and the netstat count (25) ? (genuine question, I'm puzzled too) Can you give an example of the "lsof -p 130244" output lines ? (not all 19948 please, but enough to see some variety) On 21.05.2021 16:11, Yeggy Javadi wrote: > Hi, > Here its is: > # lsof -p 130244 | grep "protocol: TCPv6"| wc -l > 19948 > > # netstat -p -a -6 --tcp | grep 130244 > tcp6 0 0 [::]:pcsync-https [::]:* LISTEN > 130244/java > tcp6 0 0 [::]:https [::]:* LISTEN > 130244/java > tcp6 0 0 [::]:37537 [::]:* LISTEN > 130244/java > tcp6 0 0 localhost.localdoma:mxi [::]:* LISTEN > 130244/java > tcp6 0 0 [::]:8009 [::]:* LISTEN > 130244/java > tcp6 0 0 [::]:rmiregistry [::]:* LISTEN > 130244/java > tcp6 0 0 [::]:http [::]:* LISTEN > 130244/java > tcp6 86 0 Yeggy-F8-FMSVA:39680 172.22.22.192:https > CLOSE_WAIT 130244/java > tcp6 0 0 Yeggy-F8-FMSVA:54772 Yeggy-F8-FMSVA:vrace > ESTABLISHED 130244/java > tcp6 0 0 localhost.localdo:42664 localhost.loca:postgres > ESTABLISHED 130244/java > tcp6 0 0 Yeggy-F8-FMSVA:54782 Yeggy-F8-FMSVA:vrace > ESTABLISHED 130244/java > tcp6 0 0 Yeggy-F8-FMSVA:54766 Yeggy-F8-FMSVA:vrace > ESTABLISHED 130244/java > tcp6 0 0 localhost.localdo:42662 localhost.loca:postgres > ESTABLISHED 130244/java > tcp6 0 0 Yeggy-F8-FMSVA:54778 Yeggy-F8-FMSVA:vrace > ESTABLISHED 130244/java > tcp6 0 0 localhost.localdo:46966 localhost.localdo:11753 > ESTABLISHED 130244/java > tcp6 0 0 Yeggy-F8-FMSVA:54788 Yeggy-F8-FMSVA:vrace > ESTABLISHED 130244/java > tcp6 0 0 Yeggy-F8-FMSVA:54770 Yeggy-F8-FMSVA:vrace > ESTABLISHED 130244/java > tcp6 0 0 Yeggy-F8-FMSVA:http 10.197.255.10:64799 > ESTABLISHED 130244/java > tcp6 0 0 Yeggy-F8-FMSVA:54790 Yeggy-F8-FMSVA:vrace > ESTABLISHED 130244/java > tcp6 0 0 Yeggy-F8-FMSVA:54776 Yeggy-F8-FMSVA:vrace > ESTABLISHED 130244/java > tcp6 0 0 Yeggy-F8-FMSVA:54786 Yeggy-F8-FMSVA:vrace > ESTABLISHED 130244/java > tcp6 0 0 Yeggy-F8-FMSVA:54780 Yeggy-F8-FMSVA:vrace > ESTABLISHED 130244/java > tcp6 0 0 localhost.localdo:45736 localhost.loca:postgres > ESTABLISHED 130244/java > tcp6 0 0 Yeggy-F8-FMSVA:54768 Yeggy-F8-FMSVA:vrace > ESTABLISHED 130244/java > tcp6 0 0 Yeggy-F8-FMSVA:54784 Yeggy-F8-FMSVA:vrace > ESTABLISHED 130244/java > tcp6 0 0 localhost.localdo:42660 localhost.loca:postgres > ESTABLISHED 130244/java > tcp6 0 0 Yeggy-F8-FMSVA:54774 Yeggy-F8-FMSVA:vrace > ESTABLISHED 130244/java > tcp6 0 0 localhost.localdo:45734 localhost.loca:postgres > ESTABLISHED 130244/java > tcp6 0 0 Yeggy-F8-FMSVA:http 10.197.255.10:64798 > ESTABLISHED 130244/java > tcp6 0 0 localhost.localdo:41016 localhost.localdo:vrace > ESTABLISHED 130244/java > Thanks > -----Original Message----- > From: Noelette Stout <noelettest...@isu.edu> > Sent: Friday, May 21, 2021 8:28 AM > To: Tomcat Users List <users@tomcat.apache.org> > Subject: Re: apache-tomcat-8.5.59 too many open files on Linux 8 > > ss has all the same options as netstat > > On Fri, May 21, 2021 at 3:51 AM André Warnier (tomcat/perl) > <a...@ice-sa.com> > wrote: > >> Soyrry to top-post, but it's getting cluttered down there.. >> >> The next thing that you may want to do : >> >> > netstat -p -a -6 --tcp >> >> That is an alternative list of sockets, which also shows the "tcp state" >> of the sockets. >> To get only the ones of the tomcat JVM PID, filter with grep based of >> the last column. >> The type of thing you are looking for is the column which should show >> "LISTEN", or "ESTABLISHED" or "CLOSE_WAIT" etc.. >> >> The options above : >> -p : show PID and program >> -a : show all sockets states >> -6 : only inet v6 >> --tcp : only TCP sockets >> >> "netstat" may not be on your system by default, and you may need to >> install it. >> An alternative is "ss", but I don't know the options. >> >> >> On 21.05.2021 02:14, Yeggy Javadi wrote: >>> Hi, >>> Yes; that is what I get and as you can see among 8028 open files, >>> 7474 >> are for TCPv6 sockets: >>> java 130244 root 7805u sock 0,9 0t0 12294251 >> protocol: TCPv6 >>> >>> # ps -ef | grep tomcat >>> root 130244 1 1 11:01 ?
