Comment(by strk):

 Confirmed. The buffer computation uses a lot of memory which may result in
 an OOM condition causing the crash.

 As a workaround you may try to compute the buffer incrementally where each
 step should reduce the number of segments opefully making it easier on
 memory.

 Something like:
 {{{
 select st_buffer(st_buffer(st_buffer(st_buffer(st_buffer(the_geom, 1), 2),
 7), 10), 30) from bad_raw_trajectory;
 }}}

 In any case this is a GEOS issue.
