Comment 6 for bug 1824981

I tried Ubuntu kernel "4.18.0-17-generic #18~18.04.1-Ubuntu". Crashed the same way on high load as the 4.15.0-47 does.

Now testing 4.15.0-48 from Kai-Heng.

Still haven't found the trigger for that bug. Seems to be load related - we're having five servers each running many threads reading/writing gigabytes of data to the share. There might be even 100+ processes trying to set a lock one the same file at the same time. Seems to get better if we reduce the number of parallel threads.
