I updated the BZ (and are now blocking 54321/tcp on one of my hosts). and verified it is not reachable. As general info: This system I am using is my LAB / Test / eval setup for a final deployment for ovirt (then 3.5) in production; so it will go away some time in the future (a few weeks / months). If I am the only one experiencing this problem then you might be better of allocating resources elsewhere ;) =20 Thanks for your understanding :) =20 Unfortunately it is true that developer resources aren't so abundant, but it is also true that memleaks should never be discarded easily and wit= hout due investigation, considering the nature and the role of VDSM. =20 So, I'm all in for further investigation regarding this issue. =20 As for your question: if I understood correctly what you are asking (still catching up the thread), if you are trying to rule out the stats polling made by Engine to this bad leak, one simple way to test is just to shutd= own Engine, and let VDSMs run unguarded on hypervisors. You'll be able to command th= ese VDSMs using vdsClient or restarting Engine. As I said in my BZ comment this is not an option right now, but if understand the matter correctly IPTABLES reject should ultimately do the same? =20 Definitely yes! Just do whatever it is more convenient for you. =20 As you might have already seen in the BZ comment the leak stopped after bloc= king the port. Though this is clearly no permanent option - please let me kn= ow if I can be of any more assistance!=20
