Right, from XrdOss/XrdOssAio.cc:
```
#ifdef _POSIX_ASYNCHRONOUS_IO
#ifdef SIGRTMAX
const int OSS_AIO_READ_DONE  = SIGRTMAX-1;
const int OSS_AIO_WRITE_DONE = SIGRTMAX;
#else
#define OSS_AIO_READ_DONE  SIGUSR1
#define OSS_AIO_WRITE_DONE SIGUSR2
#endif
#endif
```

So I'd assume the signal handlers do not get setup correctly ... or somebody spawns a thread in some plugin in a way that does not give xrootd a chance to block them for that thread. IIRC, signals can get delivered to any thread that does not block them (so one usually sets up a special signal handling thread where a specific set of signals gets unblocked).

We need a core for sure :)
