[op5-users] crash after mysql failover and importer

[nicolas.raspail at bnpparibas.com]

Hi 

I have upgraded my merlin setup to 
0.6.3-beta1-d4166ee6c2d2189b5c930c13ac7d18ff7cb4a26b, ninja-0.3.2-beta2, 
nagvis 1.4.3 and and since I have see two problems. 

1/ Crash when we issue a failover of the MySQL server
2/ When playing with nagvis or ninja, merlind seems to freeze and 
execute an import job. I have see this a lot of time

Here is some details about the first problem. I have issue a failover at 
this morning between 6h40/45 and I can see in the log :

Sep 12 06:42:11 eqd-nagios01 kernel: merlind[15381]: segfault at 
0000000000000005 rip 00002ab20f8ded60 rsp 00007fff9b662f68 error 4 Sep 
12 06:42:35 eqd-nagios01 kernel: merlind[23114]: segfault at 
0000000000000000 rip 00002b9bfc74d069 rsp 00007fffae57ce70 error 4

Later in the day, merlind crashed again but I haven't do anything Sep 12 
08:51:26 eqd-nagios01 kernel: merlind[28524]: segfault at 
ffffffffffffffff rip 00002b35767438bb rsp 00007fff347f9990 error 4

I switch again the server to its main server and merlind crashed again 
two times :
Sep 12 16:47:11 eqd-nagios01 kernel: merlind[6391]: segfault 
at 0000000000000005 rip 00002ac399026d60 rsp 00007fff11f1b818 error 4 
Sep 12 16:49:25 eqd-nagios01 kernel: merlind[24773]: segfault at 
ffffffffffffffff rip 00002ba58a3608bb rsp 00007fff20bdcd80 error 4 

After every crash, my cluster software restart it without problem, but it 
should not have crashed.

For the second problem, maybe it is related to a load problem or a
a merlin timeout somewhere ?

Nicolas
