Ongoing 7-Zip Compression Issue After Closing ComicBase

[Jeremy S]

I’m starting a new thread as the original post by Fred Slota (“Weird system hang when closing ComicBase”) appears to be resolved for them, but I’m continuing to experience the same issue despite multiple troubleshooting attempts.

Issue Summary:
After closing ComicBase (latest build, downloaded today, WIndows 11), the 7-Zip process continues running in the background, consuming significant CPU resources. This persists for an extended period (over 30 minutes), even when backups are saved locally and not to a cloud folder (i.e., OneDrive). A compressed backup file folder is created but often shows a file size of 0–1 KB, and the 7-Zip process does not terminate on its own unless I manually end it.

What I’ve Tried:

• Uninstalled and reinstalled ComicBase and its Resources
• Changed backup directory from OneDrive to local SSD
• Manually ending the 7-Zip process as a workaround

I can avoid the issue by disabling the compression, but this prevents me from being able to save the backup online.

I am wondering if anyone has any tips? This issue has only been for the past few months (since the latest major update). I am wondering if there is a process for repairing or reinstalling 7-Zip?

@Jeremy S, I've had issues with the 7Zip compression also.  Take a look at your RAM usage in Task Manager.  Browsers such as Firefox and Chrome tend to be RAM hogs, so consider closing them and other high-usage programs until the compression is done.

I don't have a full solution, but that's been my observation, so hopefully it helps.

Good luck.

Never mind; I've seen it take over 16 hours without completing (and that's with no browsers running), yet if I create the 7z compressed file by "hand", it takes 2 minutes.  Something is definitely wrong here (maybe the thread/process priority is too low?)

Thank you! I was beginning to think that it must be a problem with my specific installation.

The only solution I have been able to find is to disable the compression. If I then close ComicBase and run SIdekick, I can at least save the backup online (as it does whatever compression is required for that okay). However, the compressed local file backups are never created.

I never thought of the local file creation. If I create a WinZip file, it is pretty fast. If I manually create a 7z compressed file, it  works and completes, but takes about 10 minutes - still an improvement.

I must admit that the technically/programming elements are but beyond me, but hopefully others will have some ideas
