So, a combination of lenny kernel + wheezy rsyslog is not correctly working,
whereas squeeze kernel + wheezy rsyslog will.
2-releases old kernels are not really supported in Debian, we do our best to
support the kernel from the last release.
That said, it is still a bug, but I downgraded it to normal and retitled it.
Rainer, the epoll usage in rsyslog should apply runtime checks when using epoll
and fall back gracefully. the following was suggested in a similar situation
[1]:
#if defined(HAVE_EPOLL_CREATE1)
fd = epoll_create1(EPOLL_CLOEXEC);
if (fd < 0 && errno == ENOSYS)
#endif
{
fd = epoll_create(256);
if (fd < 0 || fcntl(fd, F_SETFD, fcntl(fd, F_GETFD, 0) | FD_CLOEXEC) < 0)
return -1;
}
return fd;
