It could be some sort of resource issue, or connection limit. I'd try less threads.

With disk and network I/O bottlenecks involved, I find it hard to believe that 40 threads would be quicker than 5, on my low spec system here 5 takes about twice as long as 1!

NAME

       max_thread_proc - defines the maximum number of concurrent threads allowed per process.

VALUES

   Failsafe
   Default
   Allowed values
   Recommended values
DESCRIPTION

       is  a  dynamic  tunable	that  limits  the  maximum number of threads allowed per process on the system.  When tuning the maximum number of
       threads allowed per process will be the new value of No process will be able to create new threads such that the total count of its threads
       exceeds

   Who is Expected to Change This Tunable?
       System administrators that run applications on their systems requiring a high number of threads per process.

   Restrictions on Changing
       The effect of tuning on existing processes is undefined.  However, existing threads will not be effected.

   When Should the Value of This Tunable Be Raised?
       The  value  of  should be raised if there is a need to run an application that requires a higher number of threads per process than what is
       currently set to accommodate.  Also, if thread creation fails with the value of then it could indicate that the has been reached.  However,
       reaching  is  not the only reason why a thread creation could fail with may be returned if the system tunable has been reached or memory on
       the system is exhausted.

   What Are the Side Effects of Raising the Value?
       A group of processes may be able to exhaust the system wide limit of threads on the system.

   When Should the Value of This Tunable Be Lowered?
       If you feel that it is necessary to limit the number of threads allowed per process.

   What Are the Side Effects of Lowering the Value?
       Some applications which need a high number of threads may behave differently or fail to operate.

   What Other Tunable Values Should Be Changed at the Same Time?
       You may want to look at the value of
