Re: [equinox-dev] equinox event question

Thanks much Thomas. 

So far, the reporter has been great about responding to requests, so my guess is he'll come up with the desired info.

BTW...others might be interested in this...the bug reporter has been using Equinox + ECF Remote Services to do some interesting work on 'Service Oriented Evolutionary Algorithms'.  See [1] for his description.

Hi Scott,

I added comments to the bug.  I suspect it is a deadlock caused by locks in the DS and/or framework implementations.  But at this point it is just a guess.  Hopefully the bug reporter can help out by generating a thread dump for us to look at.

Tom

Greetings,

We/ECF uses Equinox event for our implementation of the Remote Service
Admin specification.   One of our consumers has been using ECF remote
services/RSA, Equinox, DS and their own code, and has experienced a
problem that we are attempting to diagnose.

See the full description on this bug [1].   As you can see on the bug,
the error message that they are apparently getting when the remote
service export fails is:

!ENTRY org.eclipse.equinox.ds 2 0 2013-01-14 20:46:42.134
!MESSAGE [SCR] Enabling components of bundle org.eclipse.equinox.event
did not complete in 30000 msÂ

!ENTRY org.eclipse.equinox.ds 2 0 2013-01-14 20:46:42.135
!MESSAGE [SCR - WorkThread] Timeout occurred! Thread was blocked on
processing [QueuedJob] WorkPerformer:
org.eclipse.equinox.internal.ds.SCRManager@19336006; actionType 1

This apparently happens intermittently at startup.

Couple of questions for Equinox folks:   Does anything about this error
message (for org.eclipse.equinox.event) look familiar/understandable?    
Is it possible that a race on startup is causing this?

Also...for the DS folks...is there any option that will get DS to report
the component where the thread was blocked?   It would be very helpful
for us to be able to understand where this is happening (i.e. whether
it's consistently on a given component, etc).

Thanksinadvance,

Scott
