egrep still consumes a lot of memory for me. A workaround I've been
using is to add this to /etc/logcheck/logcheck.conf:

export LC_ALL=C
interesting - does using C.UTF-8 have the same effect?
tl; dr: no :/
According to my simple test:
# grep LC_ALL /etc/logcheck/logcheck.conf; time sudo -u logcheck logcheck -t
export LC_ALL=C
real 0m2.706s
user 0m0.005s
sys 0m0.010s
# grep LC_ALL /etc/logcheck/logcheck.conf; time sudo -u logcheck logcheck -t
export LC_ALL=C.UTF-8
real 0m9.374s
user 0m0.007s
sys 0m0.010s
The above only shows the time spent but when checking with `top`, the
`%MEM` goes up to ~47% for LC_ALL=C and reaches ~95% with LC_ALL=C.UTF-8.
