Zooko and I successfully reproduced this failure, and a similar failure for SDMF. For MDMF, the storage server is consistently OOM-killed when it approaches the 595 MB available memory of a t1.micro EC2 instance (at around 543MB resident): 

Aug 18 19:36:20 ip-10-196-59-108 kernel: [33065383.602943] Out of memory: Kill process 1662 (tahoe) score 892 or sacrifice child
Aug 18 19:36:20 ip-10-196-59-108 kernel: [33065383.602960] Killed process 1662 (tahoe) total-vm:577324kB, anon-rss:542684kB, file-rss:0kB

For SDMF, the publish fails due to a Python MemoryError at around 442MB resident. The process survives but stays at the same memory usage for a while, then drops to 281MB resident.

More details to follow.

  • Resolution set to was already fixed
  • Status changed from new to closed

This is probably the wrong place for S4 bug reports. Also the S4 deployment infrastructure has changed such that the limits discussed above no longer exist.
