Android - adb / Unable to open sync connection

I can run and debug my Android app on my phone just fine, most of the time. Then, seemingly randomly, when I try to run or debug my app from Eclipse, the Console in Eclipse says:

[2010-10-12 09:36:48 - myapp] Android Launch! 
[2010-10-12 09:36:48 - myapp] adb is running normally. 
[2010-10-12 09:36:48 - myapp] Performing com.mycompany.myapp.MyActivity activity launch
[2010-10-12 09:36:48 - myapp] Automatic Target Mode: using device 'HT01TP800561' 
[2010-10-12 09:36:48 - myapp] Uploading myapp.apk onto device 'HT01TP800561' 
[2010-10-12 09:36:48 - myapp] Failed to upload myapp.apk on device 'HT01TP800561' 
[2010-10-12 09:36:48 - myapp] java.io.IOException: Unable to open sync connection! 
[2010-10-12 09:36:48 - myapp] Launch canceled! 
  • Retry: doesn't help, same messages.
  • Restart Eclipse: doesn't help.
  • Restart adb (adb killserver && adb start-server): no errors, doesn't help.
  • Reconnect the phone: sometimes helps.
  • Reboot the computer: kind of drastic, haven't tried this yet.
Using Ubuntu 10.4, Eclipse Galileo 3.5.2, Android SDK 7, ADT plugin 0.9.6, Nexus One, Android 2.2.1.
Any bright ideas?
