Influx::DB write does not work when there are some specific values in the data

[gontikas]

Hello,
I am using this to write to influxDB.

$influx2->write($arrayref, 'database' => 'myDB');

I am using Dumper to check the data before writing to DB.

This one works:
$VAR2 = 'pdn_con_stats,host=MME1,mmepool=mmepoolc2 Failure_at_enb:\ eps_esm_cause_network_failure=17.13,Success=66.35 1535483595493004000';

Query from Influx:
2018-08-28T19:13:15.493004Z 17.13 66.35 DE2VMME1 mmepoolc2

This one doesn't
$VAR2 = 'pdn_con_stats,host=MME1,mmepool=mmepoolc2 Failure_at_enb:\ eps_esm_cause_network_failure=16.19,Failure_at_pgw:\ dns_failure=0.02,Success=68.24 1535484008168269000';

There were no influx DB entries.
