What is semmap?
Submitted by: AdministratorThis sets the number of entries in the semaphore map. This should never be greater than semmni. If the number of semaphores per semaphore set used by the application is "n" then set
semmap = ((semmni + n - 1)/n)+1
or more. Alternatively, we can set semmap to semmni x semmsl. An undersized semmap leads to "WARNING: rmfree map overflow" errors. The default setting is 10; the maximum for Solaris 2.6 is 2GB. The default for Solaris 9 was 25; Solaris 10 increased the default to 512. The limit is SHRT_MAX.
