查看SFI-1_cmm02node13_1495096946.out文件，发现调用了SFIEvent.cxx中的build函数，其中大多数build event含有138pages， 但是还出现了一些build event只有10pages.
DEBUG_3 2017-May-18 16:45:26 [eformat::write::FullEventFragment* SFIEvent::build(...) at SFI/src/SFIEvent.cxx:518] The built event consists of 10 pages.

这些只含有10pages的event对应的L1id号正好是SFI的err文件里对应的事例：
