solved EDOBJECTS (Main): lTypeObjectManagerImpl::clear 13 Deadlock? Multithread File System Issue.

[KoleTang]

This only exists in the MT version the ST version does not do this.

When launching missions, especially the first one after the app launch.  The progress bar would show no activity for 1-2 minutes.  After that initial mission, it would progress normally or very fast for several more missions.  But then might slow again.  After updating to the latest NVidia driver 532.29, that extended to several minutes.  I started looking at the log files and DCS was always stuck on the same log entry.

2023-03-14 21:02:55.871 INFO    EDOBJECTS (Main): lTypeObjectManagerImpl::clear 13

After several rounds of trials, I finally found the root cause.  I was able to get it working and created a log file with the following excerpt.

2023-03-14 21:17:55.854 INFO    TERRAIN (Main): lSystem::CleanScenes()
2023-03-14 21:17:55.854 INFO    EDOBJECTS (Main): lTypeObjectManagerImpl::clear 13
2023-03-14 21:18:13.565 INFO    EDTERRAIN4 (Main): TERRAIN_REVISION = 5124

You can see that it only took 18 seconds to complete the "EDOBJECTS (Main): lTypeObjectManagerImpl::clear 13" operation.  My only complaint about this now is there is no progress bar update during this.  There appears to be updating on the ST version.

Edited Here - Please read this

After even more of the same issue, I think I have found the proper correct cause and good workaround.  It appears to be a file system deadlock.  It happens whenever I would start a mission that used a different map from the last.  What I have found is that I can break the deadlock just by opening a folder or some other file operation.  This results in an immediate release of the deadlock situation.

The actual workaround may be interacting with the UI of another app.  I was fooled into thinking it was manipulating folders in file explorer.  But I have found that other apps work even quicker.  Simply moving the mouse across an open browser will do the same.

In addition to updating my Nvidia driver I also updated windows.  I am running Windows 11 Pro Build 22621.  I and I now believe the windows update created the exasperated issue.

 

 

Overall this has been an extremely positive upgrade to the sim.  Thank you very much.

Cheers.

got it. my post was 6 hours before your edit. glad you found your issue. windows update is clearly one of the troubleshooting steps. just search for it.

i agree that the MT, at least for my system, has been a big boost. but i never had any of the problems that others have in my 2 years with this rig..

@silverdevil I appolagize.  I did not mean my post to be disparaging.  I edited it after I read your post.  It was not directed to you.  I just wanted to make sure everyone saw my edits and the workaround if it happens to them.  Thanks for being helpful.

no offense taken. happy flying.

Yeah, this is ongoing.  I keep another app open just so I can create a windows GUI event and unfreeze the mission loading.

This has been fixed in the DCS 2.8.4.38947 release.  Thank you.
