I may have found THE or a critical line, but have no idea why this would
lead to a core dump and no idea how to solve this

When I remove the @ in front of snmp2_real_walk I'll get a few errors like:

PHP Warning:  snmp2_real_walk(): Fatal error:  in
scripts/DataCollector.php on line 89
Warning: snmp2_real_walk(): Fatal error:  in scripts/DataCollector.php
on line 89

But i also get Messages like
Warning: snmp2_real_walk(): Fatal error:  in scripts/DataCollector.php
on line 89
PHP Warning:  snmp2_real_walk(): Fatal error: Failure in recvfrom (Bad
file descriptor) (Resource temporarily unavailable) in
scripts/DataCollector.php on line 89
