Description of problem: since python had a leak (https://bugzilla.redhat.com/show_bug.cgi?id=609017), VDSM was using high filedescriptors, that may be too high for select(). as described in http://bugs.python.org/issue3392 Version-Release number of selected component (if applicable): python-2.4.3-27.el5
Technical note added. If any revisions are required, please edit the "Technical Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: Prior to Python 2.7, programs that used "ulimit -n" to enable communication with large numbers of subprocesses could still monitor only 1024 file descriptors at a time, which caused an exception: ValueError: filedescriptor out of range in select() This was due to the subprocess module using the "select" system call. The module now uses the "poll" system call, removing this limitation.
