[nsp] 7500 + PA-2CE1/PRI -balanced

[Yuval Ben-Ari]

Hi,

I am having bad luck with using 2CE1 PA on 7500 routers (2 different
routers).
Since the PA was added it is randomly causing VIP crash followed by all
other VIPs being reset. (router is not reloading)
I was told it is hardware problem, but already tried replacing most of
the relevant parts.
IOS was also upgraded 12.0(17)S > 12.0(22)S2 with no help.
Router is using dCEF, full BGP routing, EIGRP, ATM, POS, no special
features.
I am wondering if anyone has similar config and seen/haven't seen the
problem.
