Hmm, since I just looked into this on the amd64 platform, it's almost
certainly a problem with the kernel running out of virtual memory.
Our VM system uses quite some memory for housekeeping, at least
16 bytes per page on 32-bit machines plus the machine dependent stuff.
While I thought that this would mostly be a problem on 64-bit machines
(with its much larger address space, but until now similar kernel virtual
memory limits), your mail seems to indicate that at least some 32-bit
boxes have similar problems.

Ciao,
Wolfgang
