MSGCPA5305, Job QYPSSRV, file QUSRSYS/QAYPSLOG

Often we'll get a message CPA5305 regarding file QUSRSYS/QAYPSLOG:
Message . . . . :   Record not added. Member QSRV476227 is full. (C I 
9999)
Cause . . . . . :   The maximum size has been reached for member 
QSRV476227
  file QAYPSLOG in library QUSRSYS.  The record format is QAYPSLOG and the 

  member number is 1. 

Granted we could just take various options to extend the file.  But I have 
some questions about this file.

The most pressing one is:  Is there an official IBM method to clean out 
this file?  Currently it has 425 members.  And several of them date from a 
few years back.

In case you're wondering the first line from the offending member in this 
message looks like:
*...+....1....+....2....+....3....+....4....+....5.
