Have one of the ‘bad’ asterisk versions?

Removal of Asterisk 13.26.0-1 and Asterisk 15.7.2-1

Hello! Quick update for you all, we’ve removed Asterisk 13.26.0-1 and 15.7.2-1 from our SNG7 repositories today after getting numerous complaints about Asterisk instability. We want to assure you that we do test all Asterisk instances but sometimes issues like these will slip through our own QA channel. To downgrade your Asterisk 13 simply run yum downgrade asterisk13* this will place you on Asterisk 13.22 That said we think we have identified the issue and have released 13.26-3 and 15.7.2-3 …

Otherwise, when the system gets flaky, what do CPU and memory usage look like?

Hosted where? Distro or home-built? If the latter, provide details. FreePBX and Asterisk versions? System and modules up to date?
