We have a web server running Ubuntu (16.04.3), nginx, mariadb, ISPConfig with Let's encrypt. The server is running in AWS (Lightsail). We've noticed that from time to time, the server stops responsing. It might then be unavailable for a few minutes, before it starts responding again. But we've also had to restart (power off) the server and then start it again quite often. During these problems, everything stops responding (ssh, web, ftp etc). The only thing I can see from our syslog at the times it stops are some errors regaring: Feb 10 13:10:08 ip-172..... cron[1128]: /usr/sbin/sendmail: error while loading shared libraries: libpostfix-util.so.1: failed to map segment from shared object Feb 10 13:10:11 ip-172..... CRON[18077]: (root) MAIL (mailed 38 bytes of output but got status 0x007f from MTA#012) Feb 10 13:10:35 ip-172..... CRON[18147]: (CRON) error (can't fork) Feb 10 13:12:25 ip-172..... CRON[18161]: Module is unknown Feb 10 13:13:36 ip-172..... cron[1128]: /usr/sbin/sendmail: Cannot allocate memory This is a webserver with a number of live websites, so we should avoid downtime as much as possible during the troubleshooting/fixing. Looking for a Ubuntu expert that can help us out with this as soon as possible. Please let us know if you have additional questions.

Hi There, I've read your project brief and established that your AWS server is timing out on requests and becoming unresponsive. I'll be happy to resolve these issues and stabilize the environment. But it seems that you're over capacity, because a lightweight system daemon like Sendmail is complaining about memory allocation. This will require a migration to bigger server. Best Regards, Ralph

Hi there! I am a system administrator security focused with 5+ years of experience working with servers, mostly Linux (Ubuntu and CentOS). I have read your concern and i can research into your server to detect and fix your current issue and get running with minimal downtime. Probably and misconfiguration or excessive resources usage are creating high load server and stop it. I am available to fix your issue from now.

From the logs it seems server is lacking RAM. Can debug more to see who is consuming more RAM

Hi, I see you have severe memory issue, all memory consumed causing server to not responding. MariaDB consume all memory you have. I can configure MariaDB to consume less memory or create additional swap memory, but it's better if increase RAM or create additional VPS and move MariaDB to that server. If you think you have sufficient memory, i can monitor and fix server settings to balance resources. I can help you in every manner. Thanks & Regards Sandeep Verma
