The author directory shows an error message that Mark Lucas reported yesterday.
@seed[0,1] must be two integers in the range (1,1) to (2147483562,2147483398)
and usually comes from a call to random_get_seed() or
random_seed_from_phrase($phrase). at /usr/local/lib64/perl5/Safe/Hole.pm line 68.

I have a problem (/res//fsu/capalibrary/71EMWavesI/prob02.problem) that I have use for a number years but now one of the students is experiencing a randomization issue - see attached screenshot. It seems that there is an issue with the random call. (I had the same issue with another problem about a week ago. That problem is /res/msu/physicslib/msuphysicslib/70_CircAC2_LRC_Power/msuprob01.problem.) I cannot find any error message in perl/logs that seems to correlate with this error. The only thing that seems link to the issue is in /var/log/httpd/error.log - there there are lots of entries that say
Use of uninitialized value $0 in concatenation (.) or string at /usr/lib64/perl5/Config.pm line 60.
Use of uninitialized value $^V in sprintf at /usr/lib64/perl5/Config.pm line 60.
However, since there is no date/time stamp for the messages, so they may not be due to the random function. So far this has occurred two times, one for a student and another for one of my TAs.
The system that I am using is Centos 7.
Anyone else having this problem and any idea how to fix this?
