i was reading an article pertaining to an issue with Safari Here in another forum but i do not use Safari, pulled some of the data from errolog1 and googled it 

 

"shpool alloc failed" this concerns me google eludes to pertaining to gpu mining nicehash, why would nginx be trying to allocate to a "pool" or i t may have to do with AES

I have now looked at my second server and the size of the error.log file is zero bytes and on the first server it is 444 bytes.  (The first server's error.log would be zero also if I have tried to log in with the CapsLock key on!  😏  )  Both of these servers have been running for more than ten days.  Yours after one (or two) days, has a size larger than 6.4million bytes.   I would suggest that you have a good look at the contents of error.log.1 and see if you can figure out what is going on.

 

you could get the file back to your flash drive (If it would be easier for you view the file there) with this command:

cp /var/log/nginx/error.log.1 /boot/logs  

One Question.  Have you exposed this server to the Internet in any fashion?  

One Question.  Have you exposed this server to the Internet in any fashion? = yes via port forwarding for plex, sab 

the majority 85% of error.log.1 is this repeated, 

looking into the nchan portion it seems to be some type of pub sub client that i have not installed i think there is something nefarious happening

I hope someone else can jump in here with some insight as I am out of my league with this type of problem.  

 

I will say that the problem is probably in 15% of the log before the repeated lines.  They are the result of those problems.  (As I said, this log file should be empty.)  

 

I would also boot the server in the safe mode and see if the problem is gone.

Is this access for clients to access content on the server, or to access Internet resources for media? 

Access to the docker the media lives on an Unmounted NAS

@Fiservedpi wondering what ended up happening here and if you got any resolution. I just got the same error on my server.

I don't believe I ever solved it it just went away with an Unraid update
