Increasing the memory for the VMs from 384MB to 512MB didn't avoid the issue, so there's a definite leak somewhere, although this time fewer VMs crashed :) Reverting the patches and running with 384MB then works, so it's not something else added in the meantime (I ran last a few days ago, but don't think I merged anything interesting in the meantime). I'll test your new patches in a minute. johannes
