Socket Error from undefined Error: Error: write EPIPE

[mrLann]

OS: Ubuntu 16.04 LTS
Node.js version: 8.9.3

My first deployment at 4 month ago, only mining XMR, and the pool running stable.
yesterday i run a 'apt upgrade' command at my pool server and restart it, now my pool show me a lot of error like my title, and longRunner memory always 1.5 GB+.
so anybody know how to fix it?

Socket Error Time Out seems normal (I got everyday)
longRunner 1.5Gb+ seems abnormal (stuck some how). Database size = ?

[mrLann]

@bobbieltd LMDB 1.5GB now, MySQL 471MB.
But before me upgrade my server, there no error show on my console.
see this pic:

mining ports are not opened, it seems

are you sure all the modules are running fine?

[mrLann]

@shigutso what port u say? Pool or Monero daemon?
i visited my pool port at browser, it seems Mining Pool Online.

ports 3333, 5555, 7777 and 9000, you don't have these, the defaults ports for mining

[mrLann]
