Hi Daan,

I have checked logs form starting of api call, and I have not found anything 
special, But apart from error, I found one warning,

2015-02-23 13:11:46,226 WARN  [c.c.u.d.Merovingian2] 
(API-Job-Executor-118:ctx-adab6031 job-526 ctx-0585e904) Was unable to find 
lock for the key vm_instance24 and thread id 137380473

Don’t know meaning of this.

Here  are my logs,

Sonali,

this looks like a consequential error. You need to look further back into the 
log to find the root cause. The start job is the a query for results, please 
find the start for the actual api command.
