fiware - Orion goes down randomly when send entities -

i have installed orion in new machine, yum package , installing mongodb following instructions administration guide.

also, have deployed orion-instance wirecloud, , updated old orion instance 0.21 0.22.

in cases orion goes down randomly , have no idea why. version 0.21 worked perfectly, it's unstable.

i installed cron task checks if orion has pid dead, , start again, problem orion instance down 1 minute.

i send requests this:

    (curl http://my.orion.instance.es:1026/v1/updatecontext -s -s --header 'content-type: application/json' --header 'accept: application/json' -d @- | python -mjson.tool) <<eof {     "contextelements": [         {             "type": "alert",             "ispattern": "false",             "id": "myemail@dot.com",             "attributes": [             {                 "name": "alert-type",                 "type": "text",                 "value": "10020"             },{                 "name": "message",                 "type": "text",                 "value": "flooding"             },{                 "name": "status",                 "type": "text",                 "value": "100"             },{                 "name": "gateway",                 "type": "text",                 "value": "5"             }             ]         }     ],     "updateaction": "append" } eof 

and response is:

    {     "contextresponses": [         {             "contextelement": {                 "attributes": [                     {                         "name": "alert-type",                         "type": "text",                         "value": ""                     },                     {                         "name": "message",                         "type": "text",                         "value": ""                     },                     {                         "name": "status",                         "type": "text",                         "value": ""                     },                     {                         "name": "gateway",                         "type": "text",                         "value": ""                     }                 ],                 "id": "myemail@dot.com",                 "ispattern": "false",                 "type": "alert"             },             "statuscode": {                 "code": "200",                 "reasonphrase": "ok"             }         }     ] } 

and in moment, orion goes down (also happens if send update or delete).

i have ngsi2cosmos running, , show these messages (maybe problem here):

info in requests_wrappers [/root/ngsi2cosmos/requests_wrappers.py:58]:    --> put http://cosmos.lab.fi-ware.org:14000/webhdfs/v1/user/yyyyy/xxx/myemail@dot.com-alert-status-text.txt?op=create&user.name=yyyyy&data=true -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- info in requests_wrappers [/root/ngsi2cosmos/requests_wrappers.py:62]:    <-- 500 -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- debug in requests_wrappers [/root/ngsi2cosmos/requests_wrappers.py:64]:   <-- {"remoteexception":{"message":"org.apache.hadoop.hdfs.server.namenode.safemodeexception: cannot create file\/user\/yyyy\/xxx\/myemail@dot.com-alert-status-text.txt. name node in safe mode.","exception":"remoteexception","javaclassname":"org.apache.hadoop.ipc.remoteexception"}} 

how can solve issue?

edit:

echo 'db.csubs.count()' | mongo orion --quiet > 176  echo 'db.registrations.count()' | mongo orion --quiet > 0

screenshot of /version displays uptime (before that, uptime 5 days, when start using mashup, goes wrong , orion goes down).

edit 2:

installed gdb, executed ulimit -c unlimited running contextbroker -fg shell shows more detailed errors:
