Dear EPICS community,
I am currently investigating what options I have for storing the logs from our IOCs centrally.

I have set up a syslog-ng docker container for testing purposes.
The host server has the IP 10.32.240.32, the docker container has published ports 514 (UDP), 601 (TCP).

For testing purposes, I used a client in the same subnet with the command
    logger -n 10.32.240.32 "my_message"
successfully left a message.

Now I have set the environment variables (on the client) in epics-base/configure/CONFIG_SITE_ENV.
EPICS_IOC_LOG_INET=10.32.240.32
EPICS_IOC_LOG_PORT=601

In a simple test IOC on the client, I say
iocLogInit()
and get the message
epics> log client: connected to log server at '10.32.240.32:601'

I now wanted to test whether I can send a message with errlog:
epics> errlog("my message")

However, after a short time (some seconds) I get:
epics> log client: lost contact with log server at '10.32.240.32:601'
     because "Broken pipe"

Then a short time later the IOC reconnects to the log server.
log client: connected to log server at '10.32.240.32:601'

Have I overlooked something in the configuration?
I am also open to alternatives (e.g. logstash?).

Many thanks and best regards
Simon
