I am sorry to report it, but unfortunately, Eric's recent changes to DSLstats to try to provide coexistence with HG612modemstats have made the situation significantly worse for me.
The only change I made yesterday was to implement v3.92 of DSLstats. I had not, as yet, made any further changes to HG612modemstats, i.e. the new debugging versions you posted last night. So, I'm still running on the 26/08 version you previously sent me - not any of the ones downloaded from this thread.
I made the change to v3.92 yesterday morning just after Eric posted it's availability, and I used the new 'synchronise' option. Everything seemed OK up until we had to go out last night about 6pm (after your post about your new debugging download on here BE), but by the time we got back late last night, my server was running at 100% CPU, and the same processes as Kitz has previously reported were stacked up with loads of instances, viz:
cmd.exe
conhost.exe
HG612_stats.exe
isRunningVB.exe
Now, as you know BE, apart from hg612-stats.exe I have never seen those other process stacked up in this way before, ever. So, unfortunately, I'm sorry to report that v3.92 has significantly worsened the situation for me, Eric. And to provide additional evidence, since reloading the server last night, and without v3.92 running, there have been no further instances of this issue.
I will email you the logs & things BE. Sorry Eric.
[edit] And just to be explicit, I had previously been running with v3.9 and BE's debugging harvesting without any issues - but then, as I have reported above, my aging server is so slow that I had only rarely seen it 'catch up' with modemstats in time.
