It happens in function dealloc_direct in macros invalidate_block. This function is called from pager_truncate in branch when condition "if (!INDIRECT_PAGEMAP(old_size))" is true. But I didn't find why reference to freed object is kept. As workaround we can reduce kalloc_max in hurd/mach-defpager/kalloc.c to 3 to make allocator use vm_allocate always. The drawback is that allocator will allocate only multiple of vm_page_size, but this is temporary tradeoff. Till now fsx reaches operation number 14277. +6.12.11 fsx works quite long and doesn't interrupt. + ### Write own pager 6.11.11 Reading/writing for files that fit in vm_page_size works |
