Server suddenly problem
my server: Release 8.0.0.GA.5434.UBUNTU12.64 UBUNTU12_64 FOSS edition, memory: 2GB
Have been running about 1-2 month, there was no problem. Today there was a problem with log like this:

i have follow mysql crash on wiki, after follow that wiki server running well, but in 5 minutes next, the server crash again. I don't know what is the problem cause.
Thank you for help, i appreciate your help.
1. From your services log, you have memcached services running? Memcached not required for single server. You should disable memcached and proxy for single server
2. How about increasing the memory from 2 GB into 4 GB or more due to this log : Fatal error: cannot allocate memory for the buffer pool.
Thank you Mr. Vavai.
thank you for your feedback, i will try your suggestion (memcached i have install and i will increase the memory)
i appreciate that
