multiple instances' sapstartsrv processes

Hello,

After restarting SAP I regularly have multiple sapstartsrv for a single instance running:

# ps -ef | grep -i /usr/sap/SID/DVEBMGS00/exe/sapstartsrv | grep -v grep

1. Is it a bug or a classical behaviour?

2. What are the consequences of having these duplicated processes?

Basically should I care about it?

Thanks in advance for your answer.
