Libtool lock error

[Hemant Chaudhary <hemantdude.chaudhary@xxxxxxxxx>]

Hi 

While building apache, I am getting this error:

libtool: compile: Waiting for mod_lbmethod_bytraffic.o.lock to be removed

libtool: compile: Waiting for mod_lbmethod_bytraffic.o.lock to be removed

libtool: compile: Waiting for mod_lbmethod_bytraffic.o.lock to be removed

libtool: compile: Waiting for mod_lbmethod_bytraffic.o.lock to be removed

libtool: compile: Waiting for mod_lbmethod_bytraffic.o.lock to be removed

libtool: compile: Waiting for mod_lbmethod_bytraffic.o.lock to be removed

libtool: compile: Waiting for mod_lbmethod_bytraffic.o.lock to be removed

This time I am getting error in mod_lbmethod_bytraffic.o but somethime I am getting in other .o files also. What is the cause of this type of erro rand how to solve it.

Thanks
