Yesterday my 2.2.10 box crashed after 64 days of uptime.
It was stock UP 2.2.10 compiled with gcc 2.7.2.3 on Celeron 300A,
64M RAM, 100M SWAP.
That's what catched in logs:
swap_duplicate: entry e1000000, offset exceeds max
swap_free: offset exceeds max
Out of memory for X.
And after 10 minutes:

And then it hung. No VT svitch, no network. Reset button to cure.
And a lot of oopses virtually for any procees that was at that time in system
similar either to 1st or 2ns oops.
Is this already fixed in 2.2.11?
Bye,
Oleg
