Does it often crash like this?

[iZume]

My server has more than 100 online per day, I removed several consultations that ran very consistently. Maybe the server crashed by too many queries. Now it has not crashed again for this reason, but I wonder if it is possible crash for this

[maddinat0r]

That crash might be caused by an "unusual" query result the MySQL server gives back.
Do you know by any chance what query was executed before it crashed?

[iZume]

no, i not have the wrong query, but my server not has been crashed again.

[maddinat0r]

Try R39-5 since there should be a fix for that crash now.
