Hi, I am still struggling with memory mapping issues. Unfortunately I cannot give a simple test case. We have a large memory hungry programming running on x86_64 Fiasco.OC. During the initialization of memory (using sub-rm dataspace and attach mappings) we suddenly (mid-way through) get "Ipc error 16 in pagefault from 0".
Looking up error code 16, I see its L4_IPC_SEMAPFAILED which suggests that the implicit IPC send mapping of the flex page failed in the kernel. Is this correct?
Kernel func map<Mem_space> is failing but I can't find the implementation to track it further. Anyone know where it is?
Also, any advice on how to go about diagnosing this?
Thanks Daniel
Found the map<Mem_space> func in map_util.cpp (will track further). Advice on this still welcome!
