Resolved Cron Hourly Error Email: /etc/cron.hourly/plesk-php-cleanuper

[tetrahall]

Hi
I am receiving CRON emails every hour like this:-
/etc/cron.hourly/plesk-php-cleanuper:
/usr/lib64/plesk-9.0/maxlifetime: line 16: [: Unable to start builtin modules: integer expression expected
/usr/lib64/plesk-9.0/maxlifetime: line 16: [: Unable to start builtin modules: integer expression expected

Apparently executing the below command in /etc/cron.hourly/plesk-php-cleanuper
[ -x /usr/lib64/plesk-9.0/maxlifetime ] && [ -d /var/lib/php/session ] && /usr/lib64/plesk-9.0/php_session_cleaner /var/lib/php/session $(/usr/lib64/plesk-9.0/maxlifetime)

causes the errors mentioned in the emails.

Line 16 in file /usr/lib64/plesk-9.0/maxlifetime is this:-
[ ! "${cur:-0}" -gt "$max" ] || max="$cur"

How can the error be prevented, please?

Resolved:
Uninstalling older versions of PHP has solved the problem.
No more CRON messages are received!
