Hello,

from the logs, it seems to be related to curl library, I see many
reports like:

==16459== 189,318 bytes in 167 blocks are possibly lost in loss record
681 of 683
==16459==    at 0x4C26FEF: calloc (vg_replace_malloc.c:711)

==16459==    by 0xA0601C4: Curl_ssl_connect (in /usr/lib64/libcurl.so.4.1.1)

That's like almost 200KB lost in this report.

>From the list of the modules, I see you have utils and I guess you use
http query function from there, is it?

Cheers,
Daniel
