Hi Landry,
Yes, wiped that temp file, but generated a fresh one, different fd num:
50653 firefox CALL clock_gettime(CLOCK_MONOTONIC,0x7f7ffffe1d58)
50653 firefox STRU struct timespec { 44122.094371935 }
50653 firefox RET clock_gettime 0
50653 firefox CALL getpid()
50653 firefox RET getpid 50653/0xc5dd
50653 firefox CALL stat(0x7f7ffffe1b30,0x7f7ffffe18a0)
50653 firefox NAMI "/home/user/.mozilla/firefox/test/places.sqlite"
50653 firefox STRU struct stat { ... }
50653 firefox RET stat 0
50653 firefox CALL
open(0xb1f8870275d,0x10202<O_RDWR|O_CREAT|O_CLOEXEC>,0644<S_IRUSR|S_IWUSR|S_IRGRP|S_IROTH>)
50653 firefox NAMI "/home/user/.mozilla/firefox/test/places.sqlite-wal"
50653 firefox RET open 40/0x28
50653 firefox CALL fstat(40,0x7f7ffffe1780)
50653 firefox STRU struct stat { ... }
50653 firefox RET fstat 0
50653 firefox CALL fchmod(40,0644<S_IRUSR|S_IWUSR|S_IRGRP|S_IROTH>)
50653 firefox PLDG fchmod, "fattr", errno 1 Operation not permitted
50653 firefox PSIG SIGABRT SIG_DFL
50653 firefox NAMI "firefox.core"
50653 firefox STRU struct pollfd [2] { fd=16, events=0x3<POLLIN|POLLPRI>,
revents=0<> } { fd=37, events=0x3<POLLIN|POLLPRI>, revents=0<> }
50653 firefox STRU struct pollfd { fd=4, events=0x1<POLLIN>, revents=0<> }
Collapsed the stats output, let me know if the details are significant.
Please advise if you'd need further traces and how to obtain more info.
Kind regards,
