Trying to install and run mariadb-5_5_64.zip (Berrymans)...

201009 17:48:24 InnoDB: The InnoDB memory heap is disabled
201009 17:48:24 InnoDB: Mutexes and rw_locks use VMS atomic functions
201009 17:48:24 InnoDB: Compressed tables use zlib 1.2.11
201009 17:48:27 InnoDB: Initializing buffer pool, size = 128.0M
InnoDB: mmap(136249344 bytes) failed; errno 65535
201009 17:48:27 InnoDB: Completed initialization of buffer pool
201009 17:48:27 InnoDB: Fatal error: cannot allocate memory for the buffer pool
201009 17:48:27 [ERROR] Plugin 'InnoDB' init function returned error.
201009 17:48:27 [ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed.
201009 17:48:27 [ERROR] Unknown/unsupported storage engine: InnoDB
201009 17:48:27 [ERROR] Aborting

So, is this a physical memory issue, a page/swap issue, or a database engine tuning issue?

TIA as always.
