Strange....MM only has one network activity: pool API comunication. I have a rig with a extremely poor wifi connection and never seen that. What interval are you using?, perhaps you have too small interval (<60 secs) and this generates too many network activity.
I´ll try to investigate open connections.
Thanks for your reply. I am using a 600 sec. interval. Sometimes mij CPU and mem usage get suspiciously high. I sometimes get the feeling that there might be multiple processes running. So when it starts a new miner, the old one might keep doing something in the background (although i can't find anything to back my feeling up)
Maybe i should download MM all fresh and new to be sure that there is nothing screwed up in the previous download.
For me, the powershell process:
CPU is less than 25% on a pentium G4560
Memory occupped is less than 100Mb
