I have pasted error description here.

The current application triggered a termination with a short dump.
What happened?
The current application program detected a situation which really
should not occur. Therefore, a termination with a short dump was
triggered on purpose by the key word MESSAGE (type X).
What can you do?
Print out the error message (using the "Print" function)
and make a note of the actions and input that caused the
error.
To resolve the problem, contact your SAP system administrator.
You can use transaction ST22 (ABAP Dump Analysis) to view and administer
termination messages, especially those beyond their normal deletion
date.
is especially useful if you want to keep a particular message.
Error analysis
Short text of error message:
No PBT resources available in system
Technical information about the message:
Diagnosis
     The system tried to initialize the environment for processing      parallel RFCs using the function module SPBT_INITIALIZE. Here the      system established that there are no resources in the system. This
     is a configuration problem. Only those application servers with at      least three dialog work processes can be used to process parallel      RFCs.
System response
Procedure
     1.  If no specific server group name is specified for processing   parallel RFCs:
         All application servers in your system have less than three    dialog work processes. If you want to process parallel RFCs, at   least one application server must have at least three dialog   work processes.
     2.  If a server group name was specified using Transaction RZ12 for  processing parallel RFCs:
         All application servers in the server group have less than   three dialog work processes. If you want to process parallel    RFCs, then at least one application server in the server group must have at least three dialog work processes.
Message classe...... "BT"
Number.............. 834
How to correct the error
Probably the only way to eliminate the error is to correct the program.
You may able to find an interim solution to the problem
in the SAP note system. If you have access to the note system yourself,
use the following search criteria:
"MESSAGE_TYPE_X" C
"SAPLSPBT" or "LSPBTU01"
"SPBT_INITIALIZE"
If you cannot solve the problem yourself, please send the following documents to SAP:
1. A hard copy print describing the problem.
   To obtain this, select the "Print" function on the current screen.
2. A suitable hardcopy prinout of the system log.
   To obtain this, call the system log with Transaction SM21
   and select the "Print" function to print out the relevant
   part.

Answer 1

Hi,
problem is caused by the following reasons:
1. The aRFC quotas for the application servers were not configured correctly in transaction RZ12.
2. You have used a server group for the parallel RFC that does not exist in transaction RZ12. Example of a call for parallel RFCs:
CALL FUNCTION <func> STARTING NEW TASK <taskname>
                    DESTINATION IN GROUP <group> ...
3. You have entered an invalid server group name in transaction SMQS or transaction SMQR.
4. The dynamic settings of the profile parameters do not take effect. Therefore, the new settings in transaction RZ11 or RZ12 do not correct the resource bottlenecks.
Solution
1. Check the settings of the aRFC quotas in transaction RZ12 (as described in the F1 help for each field) and refer to the documentation attached in note #74141 for information on the relevant profile parameters.
Information: You can use transaction SARFC to check the configurations set in transaction RZ12.
2. In the short dump, you can use the "GROUP_NAME" variable to determine the server group that was used for the parallel RFC. Compare the value with the names of the active server groups in transaction RZ12.
Information: The default server group is "SPACE".
3. As of a qRFC version higher than 45 with supplement 11, you are already made aware of the error that occurs when you enter an invalid server group. Before this supplement, however, you must correct the error as described in solution 2 above.
