unity vsa comunity edition crash on esxi 6.7u3 random problem

hello

i'm using unity vsa 5.0 on esxi 6.7u2 and working

when upgrade 6.7u2 to 6.7u3 the vsa crash:

vsa start and as soon as it arrives at the "login form" it does not read the serial and sends these messages:

module perl_module is already loaded skipping

module authz_core module is already loaded skipping

etc etc

but other vsa unity 5.0 work on 6.7u3

only a few vsa do not work on 6.7u3, while others work perfectly

for example: i move vsa with vmotion from 6.7u2 to 6.7u3 and vsa crash when power on and on 6.7u3 is present another vsa that working perfect.

I don't understand why some vsa 5.0 don't work on 6.7u3 and other vsa 5.0 work on the same server 6.7u3

in this post I can not attach the picture otherwise you would have suffered the problem immediately
