loading big policy fails with vmap kernel errors

[Arkadiusz Miśkiewicz]

When loading big policy (40MB) then kernel 3.0.13 complains:

[wto gru 13 15:34:25 2011] alloc_vmap_area: 44 callbacks suppressed

The policy contains ~1500 HATs. Machine is 32bit and has 4GB of ram.

One more explanation. Entire policy is nearly 10 000 hats but apparmor reload complains about this one only:

/etc/apparmor.d/usr.sbin.httpd.prefork-customer-97608 failed to load

and above thing was in dmesg.

Is this still an issue with newer kernels?

[Arkadiusz Miśkiewicz (arekm)]

Didn't see this again (but not using 32bit machines anymore).

Thanks, marking Fix Released for now. Please reopen if it comes up again.
