Hello:
I currently have a Raspberry Pi 3 running an Owncloud server using Apache and MySQL. Problem is that the Owncloud server crashes regularly. I cannot access the server via SSH (using Putty). Only way to gain access is to pull the power and plug it back in. I can then access everything (Shell In a Box, Webmin except when I try using the web interface to access my Owncloud i get the error:
********* is currently unable to handle this request.
HTTP ERROR 500
Steps to reproduce
1. After re imaging SD card, use Owncloud
Expected behaviour
Log in to Owncloud, should work as it does after re imaging sd card.
Actual behaviour
******** is currently unable to handle this request.
HTTP ERROR 500
Server configuration
Operating system: Debian 8
Web server: Apache
Database: MySQL
PHP version: 5.6
ownCloud version: 9.1, fresh install
ownCloud log: Empty file
Cannot login as Admin user as I cannot access Owncloud at all.

InnoDB: Database page corruption on disk or a failed

InnoDB: You may have to recover from a backup.
InnoDB: It is also possible that your operating

InnoDB: and rebooting your computer removes the
InnoDB: error.
InnoDB: If the corrupt page is an index page
InnoDB: you can also try to fix the corruption
InnoDB: by dumping, dropping, and reimporting
InnoDB: the corrupt table. You can use CHECK
InnoDB: TABLE to scan your table for corruption.

InnoDB: Submit a detailed bug report to http://bugs.mysql.com.
InnoDB: If you get repeated assertion failures or crashes, even

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.
key_buffer_size=16777216
read_buffer_size=131072
max_used_connections=0
max_threads=151
thread_count=0
connection_count=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 346093 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
Thread pointer: 0x0
Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...
stack_bottom = 0 thread_stack 0x30000
The manual page at http://dev.mysql.com/doc/mysql/en/crashing.html contains
information that should help you find out what is causing the crash.
