------------------------------------------

             Summary: Memory leakage in stringfields.c and logger.c
                 Key: ASTERISK-26150
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-26150
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
    Affects Versions: 13.9.1
         Environment: Virtual Machine on ESXi6 (VM Version 11, 4vCPU, 16Gb RAM), OS: CentOS release 6.8 (Final) x86_84
            Reporter: Denis S.Davydov


I found on Asterisk 13.9.1 constantly leaking memory. When memory is too low, I've got from employees complaints about loss of sound on ms, its something like ``sticking'. Last two days I tried to find module which caused memory leakage. Asterisk was compiled with MALLOC_DEBUG flag. Every hour I've run script to report memory usage:

#!/bin/sh
PATH=/bin:/usr/sbin
(date; asterisk -rx 'memory show summary') >> /data/tmp/ast_memory_dump.log

Also, I've write script that parse and load memory summary into Elasticsearch. And I build memory usage graphs by bytes and allocations. Please, look at memory usage on stringfields.c and logger.c. I think this is not normal. 

I've got last three crashes described on ASTERISK-26149.
