HttpServerConnection [...] empty in -2147483648 days

[ekeih]

Hi,

currently we have a 2.9.1 and a 2.8.4 cluster. Both clusters log the following line quite often:

[2018-08-09 04:36:07 +0200] information/WorkQueue: #20 (HttpServerConnection) items: 2, rate:  0/s (0/min 0/5min 0/15min); empty in -2147483648 days

# grep -c 'empty in -2147483648 days' /var/log/icinga2/icinga2.log
3229

We do not know if the following line is related, but the 2.8.4 cluster also logs:

[2018-08-09 03:39:52 +0200] information/HttpServerConnection: Unable to disconnect Http client, I/O thread busy

The latter line disappeared with the update to 2.9.1, but the empty in -2147483648 days line is still there.

Let us know if there is anything we could do to help to find the cause or the solution.
Thank you in advance!

Expected Behavior

Instead of empty in -2147483648 days the log should contain a valid time in the future.

Current Behavior

As far as we know it has no negative effects. It seems that only the log is affected.

Possible Solution

No idea.

Steps to Reproduce (for bugs)

Unfortunately we have also no idea how to reproduce this. It just happens constantly and we do not know why.

This is fixed in #6430.

Perfect! Thank you :)
I searched for related issues but I did not find this PR.

For the record:
In 2.10.0 the change in #6430 fixed the message. We still had a lot of them in our logs without any negative impact.
With 2.10.2 the message disappeared from our logs. My guess is that the TLS fixes in 2.10.2 improved this, but I do not really know ;)
