Glad to know that the situation have improved for your workload.
Thanks for the feedback.

v5.2 kernel has many fixes preventing reconnects that's probably why
you stopped observing the original problem. The latter haven't been
completely fixed yet in v5.2.y yet. We have a patch in for-next that
aims to fix it but it haven't been sent to the mainline yet, see

https://git.samba.org/?p=sfrench/cifs-2.6.git;a=commitdiff;h=96d9f7ed00b86104bf03adeffc8980897e9694ab.

Once it is there, it should be automatically picked up for backporting
to all active stable kernels it applies to.

In the meantime, If you start hitting the issue again, please try
mount option "nohandlecache" as a workaround.
