Re: [c-nsp] [Retrieved] Fiber issue, banging my head.
I also remember some bugs back in my GSR days, did you do a bug scrub? There were several 'cosmetic bugs' where counters would increment in the show commands but there would not actually be any problems. I already deleted your original email, so I can't reference that. Are there actual performance issues or just the counters incrementing?
