Bug#299307: apt-cache eat up all the memory and SWAP
I had a similar problem. So I came across this bug report. Stats
during apt-cache search:
ijjarvin@pointhope:~$ vmstat 1
procs -----------memory---------- ---swap-- -----io---- --system--
----cpu----

Then I said:
$ sudo apt-cache gencaches
...and the problem seemed to go away; no longer swapping (and very fast
too, harder to capture it, vmstat 1 is way too lost now :-)):
