DB2 FOR LUW / DB2FORLUW / B10 - DB2

When running restore with multiple streams (Mostly when using
incremental backups)

Example

restore database SAMPLE incremental from
"/home/db2inst1/db2inst1.SAMPLE.NODE $N+1000
.CATN0000.20180505020029.001.db",
"/home/db2inst1/db2inst1.SAMPLE.NODE $N+1000
.CATN0000.20180505020029.002.db",
"/home/db2inst1/db2inst1.SAMPLE.NODE $N+1000
.CATN0000.20180505020029.003.db",
"/home/db2inst1/db2inst1.SAMPLE.NODE $N+1000
.CATN0000.20180505020029.004.db"
dbpath on '/home/db2inst1' into SAMPLE1
newlogpath '/home/db2inst1/db2restore/activeLogs/'
replace history file replace existing redirect without prompting

SQL2032N The "buffer_num" parameter is not valid. SQLSTATE=22531

Diaglog:

The number of buffer db2 automatically picked up for this
incremental restore is 1 which is less than the number of pipe
sessions (that is, 4).
