vmod_var memory alloc assert -> panic again

Hello,
In the last few days we observe some cache resets. These are triggered by mod_var while allocation memory. I have seen different bug reports regarding to this issue in the last years but no stable solution.
We use varnish 6.0, varnish_modules 0.15 with the default workspace settings.
Is their a way to debug the workspace memory usage?
Any other solution?
