Thanks for the info, is hard to filter the bad report from the good ones

So ok, i got it... HEN have some random freezes that are not related with webman, doesnt happens very frequently but is a bug that needs to be solved
To me is confusing because i dont use HEN, but i been reading reports from users that had lot of freezes, there are some that tells they cant even use HEN because it freezes always, and thats some incompatibiity with webman (but they never thought about it and they doesnt even mention if they have webman running because they thinks is mandatory to use webman)
I also have seen people reporting problems in retroarch... weird but it seems this was also caused by webman because the problem was solved when the disabled webman (this is a proof that the plugins could create conflicts with everything)
And you are right in mentioning the incompatibilities in between different backup managers, the "golden rule" i use is to dont boot 2 different backup managers in the same session, if you do it there could be conflicts in between them, what you should do is to reboot the PS3 before using the other, but this applyes mostly to multiman/irisman/managunz. The point is this backup managers creates a "payload" in memory when you boot them for the first time in your actual play session, and when you reboot the PS3 the memory is "cleaned up" (and the payload removed)
But with webman rebooting the PS3 doesnt matters, is needed to disable it manually
