Summary: nwamd locked up after switching ncps
Classification: Development
Product: nwam
Version: unspecified
Platform: ANY/Generic
OS/Version: All
Status: NEW
Status Whiteboard: nwam1-build:2009-05-12
Severity: major
Priority: P2
Component: ON daemon

Created an attachment (id=1941)
--> (http://defect.opensolaris.org/bz/attachment.cgi?id=1941)
Gzipped core file.
I did a switch of ncps, and noticed that nwamd didn't bring up my wired
interface.
Looking at the debug log it did look like nwamd was in a state that it wanted
to ask the user for a wifi network selection.
I tried running nwam interact -v, but didn't see any events.
Then I did a pstack on nwamd and found that it was locked up as in the stack
trace at the end of this description.
The last message in the logs were:
nwamd[659]: [ID 440216 daemon.debug] 28: wlan_scan_thread: no known WLANs - ask
user
nwamd[659]: [ID 383679 daemon.debug] 28: ncu iwh0 change state from
WIFI_WLAN_NEED_CHOICE (2) to WIFI_WLAN_NEED_CHOICE (2)
nwamd[659]: [ID 926539 daemon.debug] 28: enqueueing event 7 (WLAN_NEED_CHOICE)
for object (8125448) link:iwh0
nwamd[659]: [ID 596678 daemon.debug] 1: dequeueing event of type 7
(WLAN_NEED_CHOICE) for object link:iwh0
nwamd[659]: [ID 952326 daemon.debug] 1: (8125448) link:iwh0: no matching method
for event 7 (WLAN_NEED_CHOICE)
I'm attaching a core file and log.
