ADS pdf printing issue

Good Day;

I have a problem with PDF printing. Everything was working fine . The problem started when I scheduled the report RSPO1043 for spool Consistency check on every saturday. So from monday when I print PDF I am getting an error /usr/sap/<SID>/SYS/global/spoolxxxxxx.PDA file doesnot exist. I can see only three files there except .pda . I assume the scheduled report delete the old archive files.

Is there any link between .pda file and the report RSPO1041?

Also my ADS_AGENT user get automatically locked frequently , What can be the reasons for the lock?

Thanks in advance ..

Regards
