Has anyone run into an issue of Zato web-admin becoming inaccessible suddenly?
We have the following setup:
- CentOS 7
- Zato 2.0.8.rev-050c6697
- PostgreSQL 9.4
Everything starts up fine and is ok for a day or so after which the web-admin url on port 8183 becomes inaccessible.
The process seems to be running though:
$ netstat -anp |grep 8183
tcp 11 0 0.0.0.0:8183 0.0.0.0:* LISTEN 23241/python
$ ps -ef |grep 23241
zato 23241 1 0 Nov22 ? 00:00:28 /opt/zato/2.0.8/code/bin/python /opt/zato/2.0.8/code/bin/py -m zato.admin.main
we see the following connections in netstat for port 8183:
- 10 connections in CLOSE_WAIT
- 2 ESTABLISHED
- 3 SYN_RECV
- 1 LISTEN.
The only way to solve this is to restart the web-admin and everything resumes back to normal, but this has been occurring on a daily basis and there are no logs inside web-admin.log which would help us determine the root cause.
Is there a way we can investigate whats happening or going wrong?
