Help! - Client exceeded max pending messages

Hefford27 · November 11, 2017, 4:57pm

I have started getting these messages

2017-11-11 16:35:59 ERROR (MainThread) [homeassistant.components.websocket_api] WS 140629041736392: Client exceeded max pending messages [2]: 512

Any ideas ?

Thanks

Same here, started ~ 0.58

I’m getting it too but seemingly on when I use an automation to turn a few lights on based on motion being detected by a sensor…

Same here:

Started with 0.58.1 also. No other modifications made to automations or scripts, just the update. Strange.

I’m getting this too.

Same here on version 0.63. First time I see it !

Zepixir · February 23, 2018, 3:35pm

Having the same error. Opened up an issue on github. Please add your info: https://github.com/home-assistant/home-assistant/issues/12624

I get this when I reload automations from the “config/core” page.

tom_l · May 13, 2019, 9:18am

Add me to the list.

This error:

ERROR (MainThread) [homeassistant.components.websocket_api.http.connection.139906340336304] Client exceeded max pending messages [2]: 512

Is preventing me from reloading automations. However a config check passes and HA reloads without error.

phantomdarkness · July 24, 2019, 10:31am

I’ll join the party. Seeing this when nodered is loaded and I reload automations. If I turn NR off, no errors.

I removed all statistics sensors and replaced with filter sensors. This fixed this problem for me.

I had same error and I wonder if it had something to do with statistics sensors and (in my case) Appdaemon integration.

I’m seeing these errors as well. The latest is (and as usual non-descript):

Interestingly, right before this, I had a roku error:

roku.core.RokuException: b''

I included the log entry at the top because it might have something to do with the issue. But it happened a few minutes earlier, so probably not.

The Roku script is called from appdaemon and there is a corresponding error in the appdaemon error log:

I’m planning to rewrite this into a standard automation to see if that fixes anything.

Anyone see anything that can point to the issue? Is there any way to track down the exact http connection from the number at the end of error?
