Raising the limit didn't solve the probelm, I now get "conky: too many interfaces used (limit is 64)" and then a crash. I've been running fine for years, but recently started using docker a lot (with the p4lang container), and now conky on the host tends to die.
Also used Michael Stowe's fork: git clone git://git.code.sf.net/u/mstowe/winexe u-mstowe-winexe...
