sysctl, ÐÐÑÐ ÑÐÐÐ:
cat /proc/sys/vm/max_map_count
65536
max_map_count:
This file contains the maximum number of memory map areas a process
may have. Memory map areas are used as a side-effect of calling
malloc, directly by mmap and mprotect, and also when loading shared
libraries.
While most applications need less than a thousand maps, certain
programs, particularly malloc debuggers, may consume lots of them,
e.g., up to one or two maps per allocation.
The default value is 65536.
