| Description: | 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. | ||||
