I am getting core dump only for historical yellow data for some hosts.
apache log:

generates core dump.

Any one have a workaround? I tried to change the CFLAGS and recompile with gcc 4.3.4
replaced CFLAGS = -g -O2 -Wall -Wno-unused -D_REENTRANT $(LFSDEF) $(OSDEF)
with CFLAGS = -g -O2 -Wall -D_REENTRANT $(LFSDEF) $(OSDEF)
that did not help here.
