Hi All,

Since around midnight CET, my relay who was happily running almost the same amount of traffic in and outbound, has dropped to 4 Meg in, 11 Meg out according to SNMP on the host. (Cap: 10M/peak 12.5M).

Lots of messages like:

• Channel padding timeout scheduled 304317ms in the past.
• Your computer is too slow to handle this many circuit creation requests! Please consider using the MaxAdvertisedBandwidth config option or choosing a more restricted exit policy. [45685 similar message(s) suppressed in last 60 seconds]

Any suggestions what to check / verify for this? 328E54981C6DDD7D89B89E418724A4A7881E3192

At the moment, there are extra clients on the network adding some load.
