We've been running a soft IOC that talked to a number of ethernet based

devices. We've been using the auto-reconnect feature of asyn, and

generally it works. However we often have problems where a device is

unreachable on the network, and apparently asyn will try to reconnect to

it many times in rapid succession, the end result is that the load on

one cpu core will reach 100%. At this point even if the device is

reconnected to the network the IOC will not successfully reconnect.

Has any one else had this problem, or no how to avoid it.

Probably, I could turn off autoreconnect and have a record that requests

reconnects at a specified maximum rate as needed. I'm wondering if

there's some setting that I've missed that limits how quickly asyn will

attempt to reconnect.
