SAP BASIS System can no longer create spool requests POOL_INTERNAL_ERROR, Spool Full, Spool overflow

** Myself refer Note 48284
Note 48284 - System can no longer create spool requests (SPOOL_INTERNAL_ERROR, Spool Full, Spool overflow)
Symptom
Creating spool requests takes a long time. Finally, the system cannot create any more
requests and the short dump SPOOL_INTERNAL_ERROR occurs. In the dump itself and in the
syslog, the system issues the message "Spool full" or "Spool overflow".
- SPOOL_INTERNAL_ERROR
- Spool Full
- Spool overflow
Solution
1. Log on to the system in client 000 and call transaction SNRO
2. In the "To No." column, change the upper limit of the interval SPO_NUM to 999,999 (Default numbering range is 100 - 32,000 can print to 32,000 requests buffer number 100)
[Optional Task] Not sure for change optional because Sap Note not show maximum limit by profile may be ignore by sap kernel
3. Call rz10,change profile parameter rspo/spool_id/max_number up to 99000
4. Call rz10,change profile rspo/spool_id/loopbreak up to 99000 same value as above
