Hi,

I have a website installed since month now, working perfectly. Nothing has changed, no deploy etc...

But now, I test a specific query, sometime it work and sometimes it failed! It is completely random.

So, I have absolutely no idea of the problem... so does someone has an idea, or simply an idea to debug?

PS: BTW, I noticed another issue when trying to log into kibana, I have this (but not sure it is related):

{"statusCode":500,"error":"Internal Server Error","message":"[parent] Data too large, data for [\<http\_request\>] would be [524702814/500.3mb], which is larger than the limit of [510027366/486.3mb], real usage: [524702232/500.3mb], new bytes reserved: [582/582b], usages [request=0/0b, fielddata=0/0b, in\_flight\_requests=582/582b, model\_inference=0/0b, accounting=241624/235.9kb]: [circuit\_breaking\_exception] [parent] Data too large, data for [\<http\_request\>] would be [524702814/500.3mb], which is larger than the limit of [510027366/486.3mb], real usage: [524702232/500.3mb], new bytes reserved: [582/582b], usages [request=0/0b, fielddata=0/0b, in\_flight\_requests=582/582b, model\_inference=0/0b, accounting=241624/235.9kb], with { bytes\_wanted=524702814 & bytes\_limit=510027366 & durability="PERMANENT" }"}

What is the output from the `_cluster/stats?pretty&human` API?

I restarted the docker server and now it works. Other docker services were fine.  
Is there some good practice to maintain an ES instance in good health ?
