Fuse crash with FuseWriteCache

(Yaodong Cheng) #1


I would like to report one bug we met on Citrine. Recently EOSD sometimes crashed which is difficult to reproduce. After we updated to version 4.2.22, it still occurred. Today I checked the coredump file that showed:
#0 0x000000000050326e in typeinfo for filesystem ()
