eclipse 5.5 gives error sometimes?

I installed eclipse 5.5 in two red hat 8 machines. in one, everything 
works fine. in the other one I get:

[ssardina@cogrobo ssardina]$ eclipse

*** ECLiPSe fatal error: Cannot reserve stack space in alloc_stack_pairs()


strange, I did an strace and here is where the error seems to be:


mmap2(NULL, 268435456, PROT_NONE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = -1 
ENOMEM (Cannot allocate memory)
write(2, "\n*** ECLiPSe fatal error: Cannot"..., 52
*** ECLiPSe fatal error: Cannot reserve stack space) = 52
write(2, " in alloc_stack_pairs()", 23 in alloc_stack_pairs()) = 23



any ideas? Am I missing some package, library or something?

Thanks
Sebastian
