--- Comment #28 from Paul Floyd <[email protected]> --- Still hanging on 10.15. With --tool=none, 2 threads stuck in syscalls (lldb) thread list Process 462 stopped * thread #1: tid = 0x0f89, 0x00000002580c6543 none-amd64-darwin`vgModuleLocal_do_syscall_for_client_unix_WRK + 90, stop reason = signal SIGSTOP thread #2: tid = 0x0fb2, 0x00000002580c6543 none-amd64-darwin`vgModuleLocal_do_syscall_for_client_unix_WRK + 90 With --trace-syscalls=yes SYSCALL[479,1](unix:305) psynch_cvwait(BOGUS) --> [async] ... SYSCALL[479,2](unix:372) __thread_selfid ()[sync] --> Success(0x0:0x12a1) SYSCALL[479,2](unix:304) psynch_cvsignal(BOGUS)[sync] --> Success(0x0:0x101) SYSCALL[479,2](unix:305) psynch_cvwait(BOGUS) --> [async] ... SYSCALL[479,1](unix:305) ... [async] --> Success(0x0:0x0) SYSCALL[479,1](unix:397) sys_write ( 2, 0x104915590, 52 ) --> [async] ... First pthread_cond_destroy() call returned success. SYSCALL[479,1](unix:397) ... [async] --> Success(0x0:0x34) SYSCALL[479,1](unix:515) ulock_wait(operation:UL_UNFAIR_LOCK (flags: 0x1020000), addr:0x70000333f034, value:3075, timeout:0) --> [async] ... So it looks like thread 2 is blocked here SYSCALL[479,2](unix:305) psynch_cvwait(BOGUS) --> [async] ... and thread 1 blocked here SYSCALL[479,1](unix:515) ulock_wait(operation:UL_UNFAIR_LOCK (flags: 0x1020000), addr:0x70000333f034, value:3075, timeout:0) --> [async] ... Need to get gdb working if poss because I can't get lldb to make calls (like call and print with gdb so that I can get the guest callstacks -- You are receiving this mail because: You are watching all bug changes.
