Hi,

We are getting below unknown error for few services .

CHECK_NRPE: Receive header underflow - only 0 bytes received

I have checked the nrpe.conf and everything looks fine.
service management settings I have compared with the working services also and it seems same but only for few services getting this error.
Could someone please suggest on this.

Thanks!!
