From time to time I see that the "apt-get update" is hanging, which prevents the system from updating his package list. It also prevents an upgrade-script from running properly. in the process-list I see the following: Code: root 899208 1204 0 Sep04 ? 00:00:00 /usr/sbin/CRON -f -P root 899212 899208 0 Sep04 ? 00:00:00 /bin/sh -c /usr/local/ispconfig/server/cron.sh 2>&1 | while read line; do echo `/bin/date` "$line" >> /var/log/ispconfig/cron.log; done root 899217 899212 0 Sep04 ? 00:00:00 /bin/bash /usr/local/ispconfig/server/cron.sh root 899218 899212 0 Sep04 ? 00:00:00 /bin/sh -c /usr/local/ispconfig/server/cron.sh 2>&1 | while read line; do echo `/bin/date` "$line" >> /var/log/ispconfig/cron.log; done root 899232 899217 0 Sep04 ? 00:00:00 /bin/php -q -d disable_classes= -d disable_functions= -d open_basedir= /usr/local/ispconfig/server/cron.php root 899370 899232 0 Sep04 ? 00:00:00 sh -c while fuser /var/lib/apt/lists/lock >/dev/null 2>&1 ; do sleep 2; done; apt-get update root 899372 899370 0 Sep04 ? 00:00:14 apt-get update _apt 899385 899372 0 Sep04 ? 00:00:00 /usr/lib/apt/methods/https _apt 899386 899372 0 Sep04 ? 00:00:00 /usr/lib/apt/methods/http _apt 899527 899372 0 Sep04 ? 00:00:00 /usr/lib/apt/methods/gpgv This has happened a few times before and it can be solved by killing one of the processes owned by UID "_apt". It has happened on several of our systems and I can't find a cause for it. After the process has been killed, the job continues running, like making back-ups of the websites or running AWStats. I've got the latest version of ISPConfig installed and the OS is Ubuntu 22.04 LTS with unattended updates disabled. Is there a way to prevent this job/process from hanging? If you need any additional information, please let me know.
