Hello, Limpo.

Do you mean you applied the 2.4.26-om1 patch to the 2.4.32 kernel sources?

This is how I patched mig.c for my 'new' 2.4.26 kernel:

         /* send task  limits */
         m.rlim_cpu = p->rlim[RLIMIT_CPU];
         m.rlim_data = p->rlim[RLIMIT_DATA];

Why are you patching 2.4.32?

I patched the 2.4.34 sources...

However, there were problems with process migration and I've not had 
time to look into it again - I'll put my current 2.4.34 patch on:
