Unable to create raw socket for ICMP protocol
-
Hello,
I decided to make a new post about this since I am unable to understand most of the posts about it or they are clearly too old. I have been getting this warning on mutiple occassions already.
[26-May-2014 10:25:14.844] [WARN ] Unable to create raw socket for ICMP protocol
At some point the netxmsd stops and I need to manually start it. Sometimes I had to start it mutiple times before the server starts running properly. My question is what is causing this and is there a way to fix it? Thank you

Hi!
I'm currently investigating similar issue on one system. I'll post results here as well.
Best regards,

Could it be a limit on maximum allowed open file descriptors? I have seen this log message on server with many nodes, and increasing the FD:s helped. This server now reports (for root user)
# ulimit -n 8192 # ulimit -Hn 16384 # ulimit -Sn 8192To increase (at least on debian), see /etc/security/limits.conf and pherhaps /etc/sysctl.conf.
My limits.conf includes
root soft nofile 8192 root hard nofile 16384Regards,
