[op5-users] troubleshooting merlin

[Russell Jennings]

So,

I created a new VM (centos) and installed nagios then merlin in it.  
the problem i'm having is the NOC isn't getting data from the poller.  
or at least it's not ending up in nagios.

i have watch tail'd both logs on the NOC and poller.

sometimes this guy pops up and i gotta restart the one complaining:

in read_event: incomplete header read(). expected 64, got 0.
read() from NOC node noc1 failed: success     (also, this line is  
confusing with the failed : success)

other lines...
new connection inbound when one already exists. dropping old.

and in the poller:
recv(7, (buf + total), 391, MSG_DONTWAIT | MSG_NOSIGNAL) returned -1  
(resource temporarily unavailable)
Bogus read in proto_read_event() got -1 expected 524
read() from NOC noc1 failed: Resource temporarily unavailable

now, the frustrating thing, is i have another VM running debian (as  
the node) with the same config, and it works fine. both have the same  
IP, and same config, so when i bring one down and the other up, it  
works.

So at this point i have no idea how to proceed. Would like to sort out  
WHY this doesn't work because the new VM i created is going to (or was  
going to be) the deploy node. However i am out of ideas as to what to  
do or try.

Thanks,
Russell
