Meaning of warning in output log file

Output log file of the simulation I've doing writes this:

"Charm++: standalone mode (not using charmrun)
Charm++> Running in Multicore mode: 4 threads
Charm++> Using recursive bisection (scheme 3) for topology aware partitions
Converse/Charm++ Commit ID:
Warning> Randomization of stack pointer is turned on in kernel, thread
migration may not work! Run 'echo 0 > /proc/sys/kernel/randomize_va_space'
as root to disable it, or try run with '+isomalloc_sync'.
CharmLB> Load balancer assumes all CPUs are same.
Charm++> Running on 1 unique compute nodes (4-way SMP).
Charm++> cpu topology info is gathered in 0.000 seconds.
Info: NAMD 2.12 for Linux-x86_64-multicore"

What is the warning implying in general? Should I worry about that?
