[asterisk-bugs] [JIRA] (ASTERISK-27150) Periodic crash in ast_channel_snapshot_create

[nappsoft (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-27150?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=237811#comment-237811 ] 

nappsoft commented on ASTERISK-27150:
-------------------------------------

Just one question: do you have some mobile phone sip clients (for example zopier) connected to your system that are not reachable from time to time? 

I'm asking as we currently experience memory corruption issues on one Asterisk 13.17 based system as well (segfault in malloc every second or third day). The strange thing is that we only have this issue on one single virtual machine while we run Asterisk on tons of VMs on the same hardware with almost the same configuration (we provision the config, so it only differs in usernames, passwords and such things) and soft- and hardphones from the same vendors. 

The only obvious difference is that some zoiper clients that are unreachable from time to time while the registration is still valid are connected to this system.
