Frequent crashes with Insync 3.9.8

Bugs and issues
1

Yesterday my openSUSE Tumbleweed was update to Insync 3.9.8.60034.
Today, right after boot, I’m seeing a lot of crashes in QtWebEngine.

Insync itself seems to be working despite the continuous crashes, but it’s annoying nevertheless.

Here is a screenshot of the crashes, you can see there’s a lot of them.

Thank you for reporting this! Could you share the output of insync start --no-daemon?

Sure @mia !
Actually, I found out that this problem is related to the problem I reported earlier in this thread, and that is not yet solved.
Here is what I get If I start insync with --no-daemon:

As you can see there are several errors with the message Network service crashed, restarting service.
Every time this message appears on the console, I get a popup window in KDE saying that QtWebEngine crashed.

If you look closer at the log, you’ll also see this message right before every crash: /usr/lib/insync/libnssutil3.so: version `NSSUTIL_3.108' not found (required by /lib64/libsoftokn3.so).

Now if you look at my previous thread, you’ll notice that I was reporting problems with library libnss3.so, and that I had found a workaround by removing that library from the /usr/lib/insync directory and instead putting there a symlink to my system’s libnss3.so library.

So today I tried to remove the link and reinstate the original library, but if I do this, then insync does not start anymore, with the same error as reported in my earlier thread.

So the symlink is still the only way to have Insync working on openSUSE Tumbleweed, even though the recent Insync update added this instability in the networking code (and did NOT fix the original problem).

A final note: Insync is working despite the continuous crashing. When it is idle, there are no crashes at all. It’s only when it’s actively syncing that the crashes appear.

Thank you so much for the detailed information, @Cris70. Could you please send your logs.db and out.txt files to support@insynchq.com with the link to this post?

Done. Thank you @mia !

Hi @Cris70

Does Insync stop crashing if you remove both libnssutil3.so and libnss3.so (don’t create symlinks after removing)?

Yes @Kurt_Ko , I can confirm that remove both /usr/lib/insync/libnssutil3.so and /usr/lib/insync/libnss3.so solves the crashing problem!
Thank you!
