** [tickets:#1696] imm: Endless loop in IMMND when admo marked as dying**
**Status:** accepted
**Milestone:** 5.0.FC
**Created:** Tue Mar 08, 2016 08:28 AM UTC by Hung Nguyen
**Last Updated:** Tue Mar 08, 2016 08:28 AM UTC
**Owner:** Hung Nguyen
If there's an admo marked as dying (mDying is true, discardNode() will not
remove that admo from sOwnerVector.
~~~~
while(i2 != sOwnerVector.end()) {
AdminOwnerInfo* ainfo = (*i2);
if(ainfo->mNodeId == deadNode && (!ainfo->mDying)) {
//Inefficient: lookup of admin owner again.
if(adminOwnerDelete(ainfo->mId, true) == SA_AIS_OK) {
i2 = sOwnerVector.begin();//restart of iteration again.
} else {
LOG_WA("Could not delete admin owner %u %s", ainfo->mId,
ainfo->mAdminOwnerName.c_str());
++i2;
}
} else { ++i2;}
}
~~~~
That makes the while() loop in isolateThisNode() never end.
~~~~
while(i2 != sOwnerVector.end()) {
IdVector cv, gv;
AdminOwnerInfo* ainfo = (*i2);
otherNode = ainfo->mNodeId;
if(otherNode == thisNode || otherNode == 0) {
/* ??? (otherNode == 0) is that really correct ??? */
i2++;
} else {
ainfo = NULL;
this->discardNode(otherNode, cv, gv, isAtCoord);
LOG_NO("Admo Discarded node %x", otherNode);
/* Discard ccbs */
i2 = sOwnerVector.begin(); /* restart iteration. */
}
}
~~~~
syslog will be flooded with this message
