sometimes my gearman php client gets into an endless loop:

strace:

poll([{fd=8, events=POLLOUT}], 1, 10000) = 1 ([{fd=8, revents=POLLERR|POLLHUP}])
poll([{fd=8, events=POLLOUT}], 1, 10000) = 1 ([{fd=8, revents=POLLERR|POLLHUP}])
poll([{fd=8, events=POLLOUT}], 1, 10000) = 1 ([{fd=8, revents=POLLERR|POLLHUP}])
poll([{fd=8, events=POLLOUT}], 1, 10000) = 1 ([{fd=8, revents=POLLERR|POLLHUP}])
poll([{fd=8, events=POLLOUT}], 1, 10000) = 1 ([{fd=8, revents=POLLERR|POLLHUP}])
poll([{fd=8, events=POLLOUT}], 1, 10000) = 1 ([{fd=8, revents=POLLERR|POLLHUP}])
poll([{fd=8, events=POLLOUT}], 1, 10000) = 1 ([{fd=8, revents=POLLERR|POLLHUP}])
poll([{fd=8, events=POLLOUT}], 1, 10000) = 1 ([{fd=8, revents=POLLERR|POLLHUP}])
poll([{fd=8, events=POLLOUT}], 1, 10000) = 1 ([{fd=8, revents=POLLERR|POLLHUP}])

this is a socket:

$ l /proc/15007/fd/8 

lrwx------ 1 www-data www-data 64 2011-11-27 05:53 /proc/15007/fd/8 -> socket:[1763846792]

the code is:

  while (1)
  {
    ret= poll(pfds, x, universal->timeout);
    if (ret == -1)
    {
      if (errno == EINTR)
        continue;

      gearman_universal_set_error(universal, "gearman_wait", "poll:%d", errno);
      universal->last_errno= errno;
      return GEARMAN_ERRNO;
    }

    break;
  }

So errno must be EINTR?
