WampServer

The wampmysqld service keeps on terminating unexpectedly. There isn't much information logged in mysql.log. Here's whats in it:

I have tried forcing recover (innodb_force_recovery = 1) and even took mysqldump of all databases and restored.

Wampserver ver 2.5
Mysql ver 5.6.17

Hi,

MySQL is ready. What is the problem ?

Yes, I understand. Can I just upgrade to the latest without loosing any configuration and application settings?

Yes, the logs says MySQL is ready. But the wampmysqld service stops pretty randomly, sometimes in minutes, sometimes in hours. The log doesn't reflect any of that issue, it just says MySQL is ready for connection. However, Wamp icon turns orange and in the event viewer I can see following:

Faulting application name: mysqld.exe, version: 5.6.17.0, time stamp: 0x532358d8

Hi,

> Can I just upgrade to the latest without loosing any configuration and application settings?
You back up your local sites and export your databases in SQL files.
This is exactly the same procedure as the transfer between local and a hosting company.

Hi Otomatic,

I wampmysqld service terminated this morning at around 3AM. So it happened about 22 hours after last crash. I had set the service on auto-recovery, so it did start and is running at the moment. Any clue why this might be happening? Like I said, the error log says nothing.

>This is exactly the same procedure as the transfer between local and a hosting company.
I'm more concerned about PHP and plugins. I'm afraid current WAMPSERVER version 2.5 is too old, should I step upgrade or can directly upgrade to the latest?

Thanks
