Ghost "command timer expired" messages

[mstovenour]

In a scan posted here http://marc.merlins.org/tmp/mh_scan_all1/scan_all by Marc, there are quite a few instances of a ghost timer expiry. They seem to be benign until one occurs while a command is queued after a PLM busy NACK (15) response. That halts the scan state machine. Need to figure out why a timer is either 1) inadvertently left running, or 2) not correctly matched to the device / message after it expires. I suspect 1). I created a nice timeline with the following egrep command after saving off the file:
egrep "timer expired but no transmission|Scan all link tables|[Insteon::ALDB_i1] DEBUG3:" scan_all

These seem to have been cleared up so closing this issue. Reopen it if you find this in your logs.
