Since I upgraded to 11.10 (upgraded when it was beta) I sometimes get this error messages then I using the tab function i bash:
bash: fork: Cannot allocate memory
I have a lot of memory left (626 MB + almost 8 GB i SWAP).
It never happened before I upgraded, and I've been hoping that this should disappear in lates upgrades, but after some month the problem is still here.
$ uname -a
Linux klisterburk 3.0.0-12-generic #20-Ubuntu SMP Fri Oct 7 14:50:42 UTC 2011 i686 i686 i386 GNU/Linux
$ bash --version
GNU bash, version 4.2.10(1)-release (i686-pc-linux-gnu)
Does somebody know how I can solve this?
