Sorry for the delay on this one.
Backtrace attached.
After I fire up an improperly terminated expect script series, it only takes a few minutes to get this issue going.
Once present, the issue persists until Asterisk is restarted.
If I do a ps -aux and grep for the PHP scripts that are invoking the AMI connections, I see that indeed there are several scripts running.
This is the output of "manager show connected":

> {noformat}
> The only fix I've come up with is to completely restart Asterisk.
> It does not matter if there are any calls; this happens even on a system idle of calls.
> In this last particular case, these TCP warnings came back less than an hour after Asterisk had been running.
> While these are not warnings, it does mean something is wrong in this case as there are hundreds of each of these *per second*, and AMI is blocked forever for new connections (and possibly existing ones too).
> Seems like Asterisk can get into a funny state where TCP has broken down and then the system is basically unusable for AMI until it is restarted.
> However, no obvious impact to call process or anything like that - this seems to only break, as the errors suggest, TCP connections like AMI.
