CheckMK Agent on Xen don't quit

[Overlord (M)]

Hey guys
I have an issue on a Xen Server - the check_mk agent don’t “quit at the end”.

For example - if I do an “check_mk_agent” on the machine itself, normaly at the last output I see the shell again ([09:54 hostname ~]$). But here I don’t - the agent hangs.

With this I’m not able to do an “cmk -vv --debug” or get any output in Wato. I tried to restart the agent, but nothing worked for me.

Any ideas what I can do instead of an reboot?

If you call the agent manually is there any output?

Start the agent with check_mk_agent -d and you see exactly where it hangs.

Thank you for your answer:

-Yes I got an output
-the output ends at:

+ return
+ for skript in '[1-9]*/*'
+ is_valid_plugin '[1-9]*/*'
+ pattern='\.dpkg-(new|old|temp)$'
+ [[ -f [1-9]*/* ]]
+ false
+ true
+ section_checkmk_failed_plugins
+ failed=("$@")
+ '[' -n '' ']'
+ true
+ '[' -d /var/lib/check_mk_agent/spool ']'
+ '[' -r /var/lib/check_mk_agent/spool ']'
+ pushd /var/lib/check_mk_agent/spool
++ date +%s
+ now=1634026638
+ for file in '*'
+ test '*' = '*'
+ break
+ popd

This is what I got from another machine which is working as expected:

+ return
+ for skript in '[1-9]*/*'
+ is_valid_plugin '[1-9]*/*'
+ pattern='\.dpkg-(new|old|temp)$'
+ [[ -f [1-9]*/* ]]
+ false

section_checkmk_failed_plugins "${FAILED_PYTHON_PLUGINS[@]}"
+ section_checkmk_failed_plugins
+ failed=("$@")
+ '[' -n '' ']'

# Agent output snippets created by cronjobs, etc.
if [ -d "$SPOOLDIR" ] && [ -r "$SPOOLDIR" ]; then
    pushd "$SPOOLDIR" >/dev/null
    now=$(date +%s)

    for file in *; do
        test "$file" = "*" && break
        # output every file in this directory. If the file is prefixed
        # with a number, then that number is the maximum age of the
        # file in seconds. If the file is older than that, it is ignored.
        maxage=""
        part="$file"

        # Each away all digits from the front of the filename and
        # collect them in the variable maxage.
        while [ "${part/#[0-9]/}" != "$part" ]; do
            maxage=$maxage${part:0:1}
            part=${part:1}
        done

        # If there is at least one digit, than we honor that.
        if [ "$maxage" ]; then
            mtime=$(stat -c %Y "$file")
            if [ $((now - mtime)) -gt "$maxage" ]; then
                continue
            fi
        fi

        # Output the file
        cat "$file"
    done
    popd >/dev/null

What version is that agent?

Do you have encryption activated for the agent output?

[Overlord (M)]

No encryption set (just the allowed IPs) and it’s the newest agent 2.0.0p12-1. I had the issue as well with the agent 2.0.0p6-1 - so I upgraded this morning with no positive change.

Edit:
Thank you for you help - I restarted the server and the Agent is running again normally.
