I'm using Fedora 29 + KDE 5.14.5 + KDE Framework 5.59.0 + QT 5.11.3. For last couple days I'm getting lot of kdeinit5 crashes. I have no idea what is causing that crashes, there is no specific action that leads to fail. In logs I get such info:

Can anybody point me to a problem that is causing all that crashes?

Looks like a process with id 2388 (possibly another instance of kdeinit5?) has an open lock which the new process is trying to acquire. You'll probably need to terminate that other process before trying to run the new process.

I have no idea how do I start new process, moreover it does not fixed even after reboot.

Starting a new process is just running the command. What are you running that's crashing and giving these errors (or do they just happen from something in the background)?

In the crash output, does it consistently complain about locking as in that line that I noted in my last post? If so is the process ID always the same, especially after reboots?
An option for attempting to resolve that problem would be to kill the process with that id (though you should be cautious about doing so as killing processes you aren't familiar with could lead to trouble, including ending your session). To do that, pull up the process monitor using Ctrl+Exc, search for the process ID, right-click on it and select End Process. Assuming that the trouble process is another "kdeinit5" process, killing it should be fine.
