Hi Hristov,
thanks for the clarification.
I found one known problem with BPM 9.25
QCCR1I122243 - BPM 9.25 stops sending samples intermitently and does not resume
Unfortunately it requires DEBUG logging enabled for BPM to verify that it is the very issue,
but you might wanna open a case with support and request the hotfix for QCCR1I122243,
and give it a try.
Greetings
Siggi
