Explanation
 A VTAM® request
for storage from the buffer pool bp could not be
satisfied because there was not enough available storage in the buffer
pool.
 bp is the name of the buffer pool.
See the z/OS Communications Server: SNA Network Implementation
Guide for an explanation and description of buffer
pools and for general information on buffer pool specification and
allocation. 

System action
 The action depends on why the requested storage
was needed. Other messages might follow identifying the effect this
storage condition has on VTAM.

Operator response
 Wait a short time and reenter the command.
 If VTAM continues to issue
this message, enter the DISPLAY BFRUSE command. Save the system log
and request a dump for problem determination. 

System programmer response
 Verify that the operator entered
the buffer pool or CSA start options as specified in the start procedures. 
 Increase
storage as required. For insufficient storage errors, you might want
to redefine your buffer pool or CSA start options. If the start option
cannot be modified using the MODIFY VTAMOPTS command, you must modify
the VTAM start options file
(ATCSTRxx) and restart VTAM to use the start option.  See z/OS Communications Server: SNA Operation for more information on the
DISPLAY BFRUSE and MODIFY VTAMOPTS commands.
See the z/OS Communications Server: SNA Network Implementation
Guide for an explanation and description of buffer
pools and for general information on buffer pool specification and
allocation.
