- I believe this is absolutely caused by /VPM running out of 16MB address space.
- It can be reproduced every time by a simple script like:
-
- | aCollection aFileStream |
-
- aCollection := Array new: 1600.
- aFileStream := File pathName: 'log'.
- 1 to: 1600 do: [:i |
- aFileStream nextPutAll: i printString; cr; flush.
- aCollection at: i put: (ByteArray new: 10000) ].
-
- /VPM 1.4 crashes when 16 bit address space is exhausted. This space usually
- seems to include the operating system, the network, Windows sessions and
- other Space Junk.
-
- /VPM 2.0 crashes in an equally graceless fashion as the virtual address
- space is exhausted when the swapfile is unable to grow.
-
- I don't know if it is possible to ask the OS for the ammount of available
- 16bit space left, so the Smalltalk application could clean up gracefully.
