We've had a few intermittent server issues recently, last one 3 days ago and one today.
Technically one of the RAID drives appears to have become unresponsive, causing a lockup of our system.
We're looking into the issue and we may have to order a replacement drive which could cause some planned downtime in the near future.
Thank you for your understanding
We are observing continued intermittent slowdowns today and are working on the case.
We just had another restart due to a database lockup.
