On some AIX 7.3 hosts, uptime prints the day count without a trailing comma, for example up 96 days 7:43,. The AIX agent failed to parse this: it stopped with syntax error in expression right after <<<uptime>>> and never produced the remaining sections, spool files, MRPE, local checks and plug-ins. The affected services went stale.

The agent now accepts the day count with or without the comma. To apply the fix, redeploy the AIX agent.
