hi,
Here is a little modified code of the netFlowplugin.c (which is the probable place
where my netflow plugin crashes).
I have added manualy several traceEvent's so that I can localize the place where this
happens.. It seems to be getHostInfo() which causes the blow-up.. Hope it will help
solving the problem...
===================snippet=======================================
#ifdef MULTITHREADED
/* accessMutex(&myGlobals.hostsHashMutex, "processNetFlowPacket"); */
#endif
traceEvent(TRACE_INFO, "going to get dstHostIdx .....");
dstHostIdx = getHostInfo(&b, NULL, 0, 1, myGlobals.netFlowDeviceId);
dstHost =
myGlobals.device[actualDeviceId].hash_hostTraffic[checkSessionIdx(dstHostIdx)];
traceEvent(TRACE_INFO, "dstHostIdx: %d", dstHostIdx);
traceEvent(TRACE_INFO, "going to get srcHostIdx .....");
srcHostIdx = getHostInfo(&a, NULL, 0, 1, myGlobals.netFlowDeviceId);
traceEvent(TRACE_INFO, "succesfuly retrieved.....");
srcHost =
myGlobals.device[actualDeviceId].hash_hostTraffic[checkSessionIdx(srcHostIdx)];
traceEvent(TRACE_INFO, "srcHostIdx: %d", srcHostIdx);
