Issue/Introduction

The MLS poller went into overload using more than 500% CPU. The stopSS.pl would not shut it down after 30 minutes.  Stacks showed the following Spanning Association Manager threads:

#2  0x00007face2bbd92b in Aprisma::SpanningAssociationMgr::notifyAssociations(CsLscpeHandle const&, CsRelHandle const&, std::list<CsAssociation, std::allocator<CsAssociation> > const&) () from /opt/SPECTRUM/lib/../SS/libsskrnl.so.1
#3  0x00007face2bbdc7d in Aprisma::SpanningAssociationMgr::validateAssociations(CsLscpeHandle const&, CsRelHandle const&, CsAssocList const&) () from /opt/SPECTRUM/lib/../SS/libsskrnl.so.1
#4  0x00007face2bbe142 in Aprisma::SpanningAssociationMgr::connectionReconnect(CsLscpeHandle const&) () from /opt/SPECTRUM/lib/../SS/libsskrnl.so.1
