Problem summary

  • The nimesis daemon can hang when being flooded with service
requests from client machines that have incorrect cpuids
compared to what is stored in the nim database.

Checking alog -t nim -o, the user may find many log entries of:
<0042-008 NIMstate: Request denied - Method_req>

     

Problem conclusion

  • The nimesis daemon will need to perform a lock (mutex) around
any calls to the nim_log function when nimesis multi-threading
is enabled.
