Re: [sr-dev] [SR-Users] Processes blocking - troubleshooting slow actions

It is running in docker, the interval is not stable ~30sec. I know this is not related to DNS slow queries since I am monitoring them as well. I wonder what else can be intermittently blocking ... I am going to look at the TM locks and the callbacks. Not many modules used on this one, maybe Dialog module using a DB local sqlite modparam("dialog", "db_update_period", 60) modparam("dialog", "db_mode", 3) On Wed, Nov 13, 2019 at 10:43 PM Daniel-Constantin Mierla < miconda(a)gmail.com&gt; wrote: > Is this a virtual machine?
