# perl -Mbigint -e 'print 0'
NaN returns instead of 0


This error is caused by Perl module inconsistency on the Source server.


Update all Perl packages to latest available version.


Find all perls modules which uses 'BigInt' on Source server:
# find /usr/local/psa/PMM/ -name '*.pm' | xargs grep -i 'BigInt'
/usr/local/psa/PMM/agents/PleskX/  use bigint;
/usr/local/psa/PMM/agents/PleskX/ bigint;
/usr/local/psa/PMM/agents/shared/Storage/ bigint;
/usr/local/psa/PMM/agents/shared/ContentTransport/ bigint;
Edit each file and replace "use bigint;" to "use Math::BigInt;"
