Problem with net.tcp.listen[25]

[Durwin]

I have Fedora 23 with Zabbix 2.4 installed. I built Zabbix 3.0 from source because Fedora 23 currently does not have a library version required. I have 3.0 server and agent installed. Most work well. I am running both server and agent on same machine (for now). This same configuration worked well for version 2.4. The agent log for net.tcp.listen[25] says it returned 0, but sendmail *is* running. The net.tcp.listen[25] for other machines work, so it *is* the agent.

I saw in the release notes the changes in net.tcp.listen. It states inet_diag and tcp_diag kernel modules must be loaded, and they are.

Any ideas?

Thank you,

Durwin

For those with same problem, I found this.

https://support.zabbix.com/browse/ZBX-10431?jql=text%20~%20%22listen%22

It appears to be a known problem.

SOLVED: Problem with net.tcp.listen[25]

I do run updates regularly and had done so 2 weeks before. However, after running update now, net.tcp.listen[25] now returns '1'.
