TV-Server doesn't wake up to grap EPG or record scheduled shows (1 Viewer)

Ignore this thread.
[/UPDATE]

I didn't have this problem in 0.2.3 so I'm bit out of ideas.

My HTPC goes to standby as it should, but never wakes up to record scheduled shows or even to grab EPG at the time I have configured it in TV-Server Configuration Powerscheduler.

I've been trying to get at least EPG grabbing to work running only TV-Server without starting MP but with no luck.

Some logs attached where I scheduled EPG grab to be at 10.20 and my HTPC went to standby at 10.12. However, at 10.23 my HTPC hadn't woke up so I turned it on manually. Logs look like that TV-Server still thinks that it was automatic wake up instead of manual..

EDIT: The main problem seems to be the entering to the standby when the error occurs (see error.log). According to brief chat with Bavarian at IRC, it seems that it's somekind of synchronzation issue between threads. _powerManager get's set to null by Stop() but in the same time _powerManager will be still used in DisAllowShutdown.get() causing NPE. Both tv.log's I posted below have wrong dates for wake up (9.7.2008) because of wrong settings so ignore them (with these settings the server should have woke up not earlier than tomorrow

I added some debug lines to Powerscheduler.cs and found out this:

In [Powerscheduler Suspender] the _powerManager reference is fine but when [PowerEventThread] is running just before the shutdown, the _powerManager is null and error is logged.


Error log with Powerscheduler.dll compiled in debug mode

Another log with homemade logging

2008-07-08 18:15:35.750000 [PowerEventThread]: SETTING POWER MANAGER TO NULL VALUE
(before the only line in PowerScheduler.cs where _powerManager = null; is executed)

then

2008-07-08 18:15:35.750000 [PowerEventThread]: POWER MANAGER IS NULL WTF ????
(on first line in PowerScheduler.cs-DisAllowShutdown get() method)

and after that, line _powerManager.AllowStandby(); is executed in PowerScheduler.cs-DisAllowShutdown and NullPointerReferenceException occurs

So what is happening? Plugin is first stopped by PowerEventThread but it will still use it after stopping it??
