If you can't allocate swap, you can't allocate memory. sendmail, innocent, tries to access it anyway and runs into a brick wall. I see you have 24 MB of swap. Especially considering you only have 8 MB of main memory, that's far too little. I know the disk's small, but all the more reason for fewer partitions: 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 65536 0 4.2BSD 0 0 0 # (Cyl. 0 - 31) b: 53248 65536 swap # (Cyl. 32 - 57) c: 595968 0 unused 0 0 # (Cyl. 0 - 290) e: 61440 118784 4.2BSD 0 0 0 # (Cyl. 58 - 87) f: 415744 180224 4.2BSD 0 0 0 # (Cyl. 88 - 290) I'd recommend at *least* 32 MB, maybe 48 MB of swap (though the fact that you've got away so far suggests that 32 would probably do for this machine). While you're at it, I'd also recommend merging partitions e and f. > I logged out to give it a chance to catch up with > itself and that didn't help.
